exactly what i meant cam99

So where to begin?. Mrvenicess, Thank you so much for the great referral to FSP.

Matt Sorian, sincerely is great at what he does. The ecm tables from the
tune I got at powertech performance were a mess.

My car was getting 9 mpg whether it was on the highway or not, and the engine light kept coming on, Now that Matt has personally re-tuned the car, I am getting average 19mpg on the highway!, and 15 mpg city!.

no engine light yet and I have a feeling it never will come on again.

Power feels great for the extremely conservative modifications that I had done.

Matt, got a best pull of 520 rwhp. He gave me the graph from the final one which admittedly the car was a little heatsoaked, but I wanted the graph from the last pull. 507 rwhp and 522 rear wheel torque. Also this dyno is considered to be "the heartbreaker type" not a generous number giving dyno machine. the Id850 tables were all messed up, as the previous tuner told me, he used his own numbers. lol. Matt had access to complete table bases of id850 injectors which he entered in, along with the his experience of where the a/f ratio and timing should be at a/f is now @ 11.4 at wot and timing is 19 deg. previously the a/f was set at 11.9 and timing was 23 deg. Well I am extremely happy with Matts work.
from what Matt told me typically a stock Zl1 has about 440 - 460 rwhp,
So I got somewhere around a 60-80 hp gain. with great fuel mileage.
also has a max boost of 13.5 but on average it was 12 psi. If I remember correctly. Well Matt has my vote of confidence. Also talks to you as though you are a human being not as I was treated like at the other place. I could tell the whole story and complete experience that involves some very true and gut wrenching stuff with power-tech, but I am going to avoid the details and the drama, and just say Matt is the go- to - guy.
