    UnleashedBeast you still here man?

    Hey UnleashedBeast - I have a 15 GT with a 6R80 and was curious what you think about Amsoil's offerings after their latest reformulation announcement. I daily drive mine, internals of motor are stock other than OPG / crank sprocket, running on 93 pump gas with a Whipple. I love driving it...

    Official UOA thread with oil poll

    Is UB still active? I messaged him but maybe he’s not here currently. I have a 15 GT with OPG/sprocket and Whipple stage 2 but otherwise the motors stock. I’m trying to decide between switching from Amsoil XL 5W-20 to either (signature Amsoil) 5W-20, 5W-30, 0W-40 or what. Cruising, a few...

    How To: MMR Billet Oil Pump Gear's Install. **A FEW PICS**

    This is a fantastic write up - thank you! I have a 2015 and ordered these same gaskets listed - the BR3Z-6584-D / A, thinking they would work for the 2015+. Someone posted a picture of the 2015+ verison, ER3Z-6584-B / A, and the 11-14 ones are noteably shorter than the 2015+ version. That...

    Shop manuals inljne

    I ordered a monthly subscription to online shop manuals from Helm when I had my first 2015 GT. It was like $22/month. Now I can't find anything like that - ford shows monthly subscriptions but only for ALL models for like $300/month. Where can I get online subscriptions for shop manuals now...

    Latest thoughts 555 G2 vs MT street Comp

    I went with Nitto 555's , they should be here today so I guess I'll see soon enough. I have no experience with the Michelin 4's but are they similar ?

    Latest thoughts 555 G2 vs MT street Comp

    Thanks, Red. I was hoping to hear great things about MT since LMR doesn't have 555's in the 305/35/20 but they do have MT in that size. I'm planning on being there in the morning to check out their store. I'll take all the feedback I can get from folks who have either type of tire.

    Latest thoughts 555 G2 vs MT street Comp

    ive just picked up another 2015 GT and am curious (for a procharged daily driver) what is a better match - Nitto 555 G2 305/35/20 or MT Street Comp 305/35/20 ? I want great street traction and as long of mileage as I can find for getting about. It's a vert so I probably won't be at the track...

    ProCharger belt shredding

    So - when I first installed my stage 2 procharger with a D1SC, it came with the dedicated 8" drive pulley and the 5" blower pulley. The belt supplied (and the identical replacement I bought "just in case" before the install) were way too short for the kit. It shredded that and my spare while I...

    12v Power Source

    I'm planning to try installing a couple mechanical gauges in place of the factory ones in the center dash area above the touchscreen. Is there anywhere convenient to source 12v power that only comes on when the headlights are on? Or someplace not convenient, even? I want the gauge lighting to...

    2015 GT Oil Temp

    Does anyone know the normal oil operating temp for the 2015 GT? Or the range they see in oil temps on theirs? Curious to see what you're seeing, as I'm probably installing an oil temp gauge soon.

    Strengthening the driveline

    So, at this stage i find myself with an S550 MT82 car with a blower that loves to spin the tires in the first three gears enough to be slower in the eighth mile than it was stock. To run and leave the box on slicks or drag radials, I now have to have real concerns about being able to drive it...

    Dyno pull on 10psi

    Still got lots of tuning left to do, but I thought I'd share this video for the heck of it. 612 / 486. Long ways to go ! https://youtu.be/MAVnJckOa24

    Knock Sensor Activity

    I've noticed that my car with a CAI and Bama tune and then subsequently with a D1SC ProCharger build up both seemed to want to take less timing than most GT's. I don't EVER hear any audible knock, and believe me I listen. I keep thinking it's got to be one of 3 things: 1. An engine/vibration...

    JMS FuelMax Voltage

    I thought I posted this from my phone, but I guess it didn't go. Is anyone running a 2015 Mustang GT with a JMS FuelMax pump booster that has it set to run 18v all the time? Just curious as to whether its a good idea or not. I was reading up and a couple places including Kenne Bell say that...

    Some success, in progress

    I've got everything bolted up and the "initial tune" in, but I shredded the kit belt and the spare I bought because they were entirely too short. I had to source a 6-rib belt that was an inch and a half longer and it seems to be working fine now. Now I've got correct length 8-rib belts on the...

    Fuel pump fuse JMS Fuelmax

    The body diagrams for the 2015 Mustang show the fuel pump fuse as being number 49. It says mini fuse, 30A, but I guess it's not quite what I thought it would look like ( I think mini, I'm thinking small blade fuse type). The JMS fuelmax pump booster says to replace the factory fuel pump fuse...

    ProCharger Silicone hoses

    HELP!!!! I am trying for the life of me to get this silicone 90 degree bend hose onto the air inlet on the blower. FML. I've tried stretching it by hand, by foot, with a breaker bar, manhandling it, greasing it up with water, dish soap, hand soap.. to no avail. It's almost like it's a...

    Clutch install changed shift gate position??

    So I was getting intimately familiar with my 6-speed GT shifter and despite the negative aura it seems to have, I never had any issues at all missing gears or finding the right gates the way it came from the factory. Until today. I had a clutch installed and immediately upon driving it I...

    Draining coolant in 2015 Mustang GT with PP

    So I was diligently going about getting my car ready for my power adder install next week and went to drain the coolant. I put it on stands, got under it and got the lower engine cover off, put a 3/8" hose on the petcock drain area and opened the petcock. I also had removed the overflow tank...

    2015 gt pp 6m

    It WASN'T raining today so I went back to the track and first run out of the box with no changes from last time was a 12.908 @ 112.03. Still a 2.118 60' time and it still spun 1st, some in 2nd and brief amount in 3rd. I'm much happier with being able to say that at least it's out of the 13's...

    Differential chatter after switch to AMSOIL

    I switched over tonight to AMSOIL 75W-140 severe gear. Slow rolled it to a parking lot and did some slow circles and turns. When the clutch is engaged and the rear is under load (light load) no noise. When I put in the clutch, during a turn, I can hear repetitive clunking back there, guessing...

    T-Bolt upgrades?

    I have seen people posting about upgrading to t-bolt upgrades for their pressure side on their FI cards and was curious if it's a good idea and/or necessary. I'm pretty sure I can source the t-bolts at Napa close to home if it's worth the time. Does anyone run/not run them or have good/bad...

    2015 GT Clutches

    I was looking to get a Spec clutch for my 2015 GT but their part numbers online and via phone don't go up to 2015 yet. However, Lethal Performance is listing clutches from them for the 2015 GT, but at the bottom of every item description it says "Use of Spec flywheel required." Does anyone...

    170 thermostat swap

    I'm going to be swapping my thermostat to a 170 unit from Reische, and was curious about other Mustang owners' experience with bleeding out air on the Coyote motors, particularly the S550 if anyone's been through it yet. I was going to reuse the almost new coolant, but might drop it down to 30...

    ID1000 injectors on 2015 GT

    The ID1000 injectors came in a box that also had some plastic connectors and what looks like molex pins and rubber boots. On the 2015 I thought they were plug and play out of the box, do I need to modify my stock wiring harness to use these? I haven't had a chance to look at my stock one...
