I went to the dyno happy with the numbers.hp 268.88 max torque 258.37 max. All I have is the v2 and a ypipe no exhaust or tuning just the s/c stock pulley and ypipe and i am auto . But they told me I am running lean between 15 and 14 which I cant honestly say I know what that means heard it should be around 12? They told me I should get a fuel pressure gauge to see if I need to add fuel pressure or injector cycle with an s/afc. I have the fuel pump and fmu that came with the kit should I change the disk? btw if someone want to post the dyno sheets for me I can scan them and send them to there email I would be very grateful thanks in advance for any opinions or your help.

I know that smart dyno shops shut off the pull if the a/f goes past 13 on FI applications. I think your FMU is not adding any fuel when you boosting.

I know the fuel pump is working but I don't know how to check if the fmu is adding fuel how could I check that? btw I guess I did not go to a smart dyno shop they did 3 pulls

What, they could have blown your motor. Anyway I hope you have a fp gauge. With a FMU your psi should be in 80-90s. Which pump are you running?

i am not sure on the fuel pump its what ever comes with the stillen kit. i just bought a cartech fmu and will be geting a safc next week.
