[87fcoupe]

Hey guys I have 2007 Mustang GT/CS w/5 speed(manual)..I have cosmetics mods on the car also I have demelot tuneable cold air kit with sct 2 tune by Brenspeed.I ordered(yesterday) Kooks longtube with X(0ffroad)pipe and (new) mid muffler system from Pypes..Also got Steeda UDP and set of FRRP 4.10's gears with Hurst shifter.I will recieve all of this by Friday..Also getting new tune for my new parts.My question is that I am going to switch all the fliuds(motor tranny rearend) to Royal purple) and have it Dyno tuned when everything is completed.How much power should I have when everything is completed.....I will have everything done by monday including a custom tune on the dyno......Thanks..

I'm just being honest, my numbers are unusually high based on what I've seen from most cars.

Well considered all I hsve is a sct 2 tune by Brenspeed & Demolet CIA..With that I dynoed 296rwhp & 314 wrtq...So I think that it will be more 320's to 330's rwhp....

YES!!!!!!!!!!!!!Just recieved my order from Brenspeed,everything is here..Soon to be installed and dyno tuned..Thanks Brenspeed..

320 is my guess, but that is only because Ive seen a good friend of mine get 316 with full exhaust and about all the bolt ons.

Well, I have a 06' Roush and stock it was 362 at the wheels after exhuast, which was ford racing headers,off road bassani X and flows, it came to 403, I know I'm s/cd but I think you can gain a good 25 at the wheels.
