Looks like you got it all. Now lets start a guessing game on peak HP. I'll go with 422 at the rear wheel.

I think what 5.0 meant was its the same engine in the 302R & it revs above 7800

The JPC Racing 2011 GT made 507 rwhp with:

Stage 1 CNC ported heads and cam (similar to the stock Boss heads/cam)
Boss Intake Manifold
CAI
Tune
LT Headers
OR X-Pipe and Axle back

I would hope your car is at least in the ballpark of that figure.

Also, what was the point of revving to 8250? The stock Boss hits its peak at 7400 and I doubt bolt-ons push the peak up by more than a couple hundred RPM. Not saying the motor can't take it, but I sure wouldn't want to be the FIRST person to push it 750 RPM over the stock redline on a brand new car.

what dyno was that on? same type this shop uses or different? i thnk they said this shop uses a mustang dyno, the one you mneton a dynojet? seems to be quite a difference between the two. man to think that this car might be putting down numbers like that with nothing but a CAI, tune and x-pipe gives me wood.

i have read somewhere that the hp was still building when the car hit fuel cut off stock, not sure if that is accurate or not. I've also been looking at every in car vid i can find from press day, i have seen more than one of those vids show telemetry that appears to be over the stock redline and those cars were on track key tune. i would bet the track key ups the redline, ive seen the glint in the eyes of those guys talking about it and telling people it improves things, but by how much they have to find out for themselves.

I think that's a little optimistic considering the car made 360 stock. A 140 hp tune? Not happening.

Tune, headers, CAI, X-pipe, and axlebacks.

Still won't net 140hp, but the 360 baseline smacks of typical tuner shens as well.

Are you implying that a tuner would understate the original dyno numbers to make his tune look better?

yes considering the Boss makes more hp and yet it dynoed lower than the average 5.0

this. Lund has NOTHING to prove. he is a god of tuning. Evo has built plenty of project cars and has nothing to prove with this car. They're not some fly-by-night start-up shop.

my guess is a 80whp gain - 440.
