After I had my car dyno tuned, it appears the IAT2 temperature data is now a different PID called call MCT (Manifold Charge Temperature). I believe the local tuner was using HP Tuner software. Although I can see the MCT data via the SCT X4 tuner and the LiveLink software on my laptop, I no...

Just had my VMP Stage one kit tuned locally. Same shop dyno car at 560 RWHP last year, now 605 after their tune. Shop noticed passenger side spark plugs have some carbon on the plugs, while none of driver side do. Shop seemed to think the passenger side catalytic converter may be failing and...

Was finally able to take the Mustang out to the local drag strip (Bandimere) after installing the Gen 2R Stage 1 kit last year. I was somewhat disappointed with a fastest time of 12.8. However, this seemed to roughly the around the same speed the stock 13-14 GT500’s were running. This is my...

After installing a VMP Gen2R last year, I noticed this coyote spins up much faster now. As a result, I encounter the occasional issue where I can’t shift gears at higher rpms...clutch pedal occasionally sticks to the floor. This problem may have been present before the VMP install...I just...

I tried replacing this O2 sensor today, but couldn’t obtain enough slack in the harness in order to get my hand in in order to disconnect the sensor from the harness. I followed the instructions in the service manual except for the removal of one clip that’s near the top of the manual...

After putting the VMP supercharger and tune on earlier this summer, I just noticed the amount of fuel being reported by the trip meter seems to be off quite a bit. Although I don't expect it to be spot on, my latest numbers are almost off by two gallons...in reporting more fuel consumed than...

Cheers, I have been having intermittent P219A codes pop up that would eventually trigger a CEL. This was after I installed a VMP Gen II R supercharger with the JLT 3.0 separator. In looking at some of the Ford literature, injector issues and/or vacuum leaks in the exhaust/intake/PVC system...

Odd issue. The information center on my 2013 GT Premium just stopped showing the data...not displayed...i.e. no text. The background colors show, and the background colors change as I scroll through, but not legible. The gauge cluster (fuel, speedo, etc) function correctly. Turned car off...

Finished install last week without issue. Drove to work and such for three days without issue...about 75 miles. Beyond Supercharger, engine is stock except GT500 mufflers. Drove car about 175 miles to Steamboat Spring and when coming over a 9400ish foot pass, wrench icon popped up and went...

Finally near the end of this install, but ran into a stumbling block...can’t figure out how to remove the pin from the connector in order to solder the new wire to it. Peering down into the front of connector, I don’t see a locking pin to depress. Is it part of the connector? I looked at the...

I'm getting ready to install my VMP Stage 1 kit and oil pump gears next weekend. The install instructions seem pretty clear...already printed out. As I wait for my final parts, I had a few initial questions: 1) I bought a timing cover that has already been modified. I want to install the...

Has anyone else have a problem where the visor mirror cover will not close properly so the light will not turn off? It appears to be part CL3Z-1504098-AC @ $52. Seems a little pricy, might be a pain to find one used.

I want to finally pull the trigger in adding a VMP / Roush blower this summer for a extra kick in power to help offset the loss of power at altitude in Colorado. I believe I will install it myself...doesn’t look overly complicated if I take my time. I’m more concerned with reliability and...

Finished the Koni/Eibach/MM CC plate install this weekend and took it to an alignment shop today, along with the instructions. In performing the alignment, the tech couldn't get either side to meet the stock spec of appox -0.7....couldn't get any more positive than -1.4 on either side. Curious...

When installing the fronts struts, should I install bump stops , and the dust boots from the old struts? The instructions and videos I have seen online don’t seem to show them in the installation. In looking at other performance struts (Ford Performance / Bilstein), they appear to use them I...

Looking to do a few autocross events this summer, but want to make a few tweaks. I’m curious as to what would give me a better bang for the buck....tire change or suspension upgrade? I can only do one this year...other next year. I currently have the stock suspension, along with Michelin A/S...

I have a 2013 GT with 285/35/19 and 265/40/19s. I put Brembo brakes on the front and upgraded to larger rotors on the back. I overlooked the fact that my spare may not fit over the Brembos, so I am looking for a package that would fit in the spare tire spot and may minimize its height so it...

I am looking to reduce the large wheel gap that I have at the rear...it seems to be more pronounced after I upgraded my rims and tires. Since I am happy with the front height, I am looking at purchasing the Ford P springs but, only install the rear springs at this time. I have seen a few folks...

I installed the 4-piston Brembos today, along with the GT500 rotors in the back via the adapter. I tightened the bleeders snug, but didn't crank down on them...I couldn't find a consistent torque spec online, nor the ford instructions. Found everything from 75 to 150 in/lbs. After the test...

I should probably just call Ford Racing Parts for the answer, but thought I would ask the group. I have been purchasing the parts individually vs the M-2300-S kit as I was able to find the calipers from Ford and I wanted different pads/rotors. I am installing the 4 piston Brembos this weekend...

Has anyone actually used one of these on their mustang? Seems like it would have to lift by the pinch weld. Pros / cons? I would prefer a beefier lift in the garage, but don't have the room. http://www.stangtv.com/tech-stories/other-tech/diy-projects-at-home-are-easier-with-quickjacks/

Instead of having to pull the axles to replace the brackets so I can install the larger 13.8" rear rotors, has anyone used the adapter from Baer EradiSpeed+2 or the ebay user ncmustangparts? The ncmustangparts adapter ($130+rotors) allows one to use their same calipers with the larger GT500...

Getting ready to change out the brake fluid in the car and since the fluid is clear, it is difficult to tell when the fresh fluid has worked its way down to the brakes. I would like to know how many oz I should expect per wheel as I will have a bottle connected to the wheel as I bleed them...

Installed new rims and tires at Discount Tires with new seniors from DT. Was going to reuse the OE ones, but DT thought they were doing me a favor as they messed up my tire order. Still have old ones. Whenever we get into the car first thing, the low tire light will come on, but then go off...

Planning to run a single track day at local 2 1/2 mile road course...probably 4 sessions of 10 laps each. Don't have the track pack and limit rpm to 6500. Is it worth the trouble to run amsoil 5-50 before switching back to amsoil ss 5-20 before winter? have run a few HDPE events in past with...
