Any of the reputable tuners ( Lund, AED, PBD...) will be good and will tune you right. 650-700 on 91+ tune. As far as driveability, the thing I love about Centris is that you won’t go into boost under normal driving especially with a A10. But the power will be there as soon as you go WOT. The only difference will be the sound.The car made 525 RWHP at 7K today. 433 RWTQ. I know these are low numbers compared to what I was expecting but it runs very good. It seems faster than my Bullitt with a Whipple making 675. I guess it is the A10. Lidio at Alternative Auto took it for a ride and commented on how well the tune and blower worked. He said with 6.5 of boost he thought it was decent.
I asked him if it was making 10 psi and he said likely another 100 or more HP.
The thing still holding me back from upgrading is my concern about drivability. You might think this is crazy but of the 5 FI cars I have owned so far, this is my favorite and it has the least HP. So, I think I may end up becoming a Procharger fan.
Those of you that have experience with Procharger, if I add injectors, pulley, and boostapump if needed, who would you use to tune? What power then would it make sticking to 91+ octane?
