I wonder if he got a WB or tune.

I didn't get a WB but when i replaced the coils and got rid of the miss i took it too the dyno the next day to see what my a/f's were and if it needed to be re tuned. It made 328whp loosing 4psi somewhere and a/f's were between 12.1 and 12.5 and it seemed to run great so no need to re tune it.

I thought on FI engines you were supposed to be closer to 10:1 and only lean it out to 12 if you have hard core knock detection hardware and detonation prevention measures like meth injection!

Im not sure but my friend with the dyno said everything was good numbers wise besides the boost loss. I need to put those ES mm's that have been in my closet for a year because that motor rocks like a s.o.b.

The afr numbers are good for peak power. If the tuner says there was no knocking at those afrs then there has to be something else going on. I wonder if it is an injector problem.

Something's up because it's on an 11psi pulley and only making 7.5psi WOT until 5500 and then dropping 1 more psi till redline The car made peak power @ 5500 when it should have been 6400.

did you eliminate belt slip?

I haven't had a chance to snug it up but im thinking the 1 psi im loosing @ 5500 is probably belt slip but the other 3 or so idk.

Yeppers Im working like 55 hours a week so i really dont have the time nor the ambition to get around to doing it lol. I am going to get all new charge piping and couplers and snug the belt up and hopefully that works. The dyno pulls pissed me off a little too because it made peak @ 5500 due to the boost dropping off but idk. I only drive it once or twice a week now so it doesn't bother me too much.Crossing fingers
