i have a 03 cobra an it has a small (2.3) s/c pulley,s/c idler pulley,cold air intake,off road h pipe,flowmaster cat back,and a download from the dibalo sport tunner....the problem is i can smash the throttle cause when i do it acts like its not gettin air or fuel one,now if i ease into it an get up to around 3 grand i can punch it an dont have a problem its just seems to be in the lower to mid range rpms.also the gas cap light came on an i replaced it an it fixed it for a few months an now its back on?anyone have any ideas ????????

I hope to god you have a dyno tune with a smaller pulley on their and are not using the sh*tty canned tuned that came with ur diablo. Also what is your Air/Fuel at?

2.3" pulley?? ...anyone heard of that? ...I would think that pulley would over spin a Eaton!

+1 on the A/F ratio & tune!

^^ I just spent about a half hour looking at all the manufactures that make pulleys for our cars and I can find one that makes a 2.3

2.3 pulley will destroy an Eaton. I'm sure he's mistaken... Either way, get that ****er on the Dyno ASAP before you blow it the **** up...

Timspony

2.93" maybe???

i do have the diablo tune in it ive herd bad things about it as far as the pully i was told it was a 2.3 ill measure it to be sure tho an there is no a/f meter in the car yet ive been looking into this dyno shop in akron ohio called akron horse power they want 600 for a dyno tune is that a decent price?

that is way over priced imo dayton 5.0 performance tuned my cousins car for 350

That's just dyno time alone. I'm sure they were quoting him for a chip or programmer PLUS dyno time...
