Lol, I actually almost asked if this was a V6 with a blower with those numbers! But then I figured I would give the O.P. the benifit of the doubt. Send us a pic of the engine O.P.

Agreed terriable, I dynoed at 423hp. With a Procharger.

i am thinking it might be a V6 with a Roushcharger, a fake dual exhaust and GT badging...

check the VIN to make sure it's a V-8...

...either that, or you are not hitting full throttle (check the TB) or not getting boost

haha, i thought bout a v6 too but i am 100% positive its not.... took the dude that does the install of the s/c at another dealership here in town for a ride and just by seat of the pants he says it feels just like a roush vehicle(427) and other roush superchargers he has installed. could it have been a dyno prob? i know dyno doesnt lie but i know i got more power than 243...heres a pic under the hood....

Go to a different shop that has done other Rousch installs,
have them inspect it,
get a custom tune done,
get redyno'd.

Good luck

I'd still want someone else to check it out (like a tuner shop).. but, since it has factory warranty you can rod it hard and if it blows they owe you a new one, so you could race someone... try to find someone that would definetly beat a stock GT (since your numbers are much lower than a stock GT) and if you beat him then you'll know the dyno was wrong.. or to the track like someone said.. i think you should run like a12.5 i'd guess.. and with the dyno results you should run like a 15.. (guesses)

I would get a print out of the pull, showing HP, Torque and AF and then fax it to Rouch followed up with a phone call.

What state are you in? I would definitely take it to another dealer that is VERY experienced with Roush. I know the guys here hate the Roush but I'm totally happy with mine. I have an 06 GT that I added the Roush SC to and just recently added a Steeda intake and Justin VMP tune. God the SC is loud now but it really runs. Ran a friends automatic GT500 last night and beat him by about 2 lengths. (he spent a lot more than I did)

Naw man I meant like your numbers and mine, stock numbers, its obvious his sh*t aint right lol

Yeah what the fack its acting a restriction actually pulling power from the motor. about 15-25% like it does soak up. Even if it was a v6 it would be making over 300.
