People, please carefully re-read the OP's first post.

He is making 250whp at 3800rpm. Once he gets the fueling issue sorted out he should def see 300+whp.

I highly doubt that shop is better if they are having issues with "fueling" at 4k rpms, roffle. Hptuners by recommended members > shops who don't know our platform.

Also without high octane on the TVS you won't ever see it's true potential. Either use e85 or meth.

Torque is looking good. Should be able to get quite a bit more power out of it though. Do you know how much timing they are running?

I wouldnt remove the MAF. Our ECUs dont have a whole lot of control when it comes to speed density tuning. Also, on our cars the MAF can read to ~16,000hz so if he was saying get rid of it just because you may be going over the 11,000hz control limit there are ways around that other than deleting the MAF.

Damn man I totally would have if I had checked this earlier haha. And the only reason they were having problems with your fuel system is because you have the return style system right? Also, how did it turn out? Did they do a good job? And was it a dent to the wallet hahaha

it really wasnt i problem, i t seemed like it to me cause im not a tuner. but he was just doing it bit by bit because he couldnt find a map for my setup up to start off with. i think it turned out great and they are awesome people to work with. im going to go back to them to get my clutch put in. looking at my hp curve on the sheet he did show me how my pos exhaust system restricted horsepower. but it only costed me 500 and i hung out there all day jsut bullshiting with them
