Approxamatly 500 hp, it has never been on a dyno. I have well over $20,000 into the drivetrain. "


ok thats alot of stuff right!!! and it should fly if it had wings but (and i'm a first time sy owner) it dosnt feel now where close to "running" it has a sputter on take off doesn't keep you in back of your seat till i let off the gas.

so i think it might be a combination of to much or not enough gas,spark,fuel, air, to big of injectors????????? the guys that supposedly fixed it/installed the 96 heads. tuned it in and well like i said its not where i think it should be.
so if anyone has any ideas or knowledge about how to go about this please let me know. im in tucson, AZ now.

Trailer, northern California, Advanced Dyno. Robert is a genius on the dyno. Especially with forced induction and nitrous tunes. Make a short vaca out of it.

Re: still need help

Wow, looks like you have a lot of nice mods, what have you done so far as tunning and tune up, "sputtering" sounds like ignition related?

Re: still need help

man the guy that "tuned it" did the fast management and supposedly everything needed???
 
Re: still need help

You really need to get some sort of scan tool (tunerpro, tunercat, datamaster, etc.) so you can see what's going on. Take it from me I just spent $5k on a new motor because I wasn't "sure" what was going on, and I drove the snot out of it. Don't do what I did!!! Drive it as little as possible untill you know what your motor is doing, or you WILL be bummin!!
