yea, tested the fuel pressure today, the highest it goes on boost is 45 psi, it should be more like 60 psi. we are gonna use an aftermarket fuel press regulator to up the pressure to say about 60...

yeah I was gonna say I have the 850/1300 combo which is good for 475 hp or so and I remembered the 1600 secondary setup was supposed to be right around there or even a touch higher.

that power band is stretched out too far. I would like to be making power sooner.. thats definately a weird curve. It makes peak hp at the last minute... I want my peak somewhere in the middle. Get that turbo to spool faster.. was that a 4th gear pull ??

the powerband is weird, because in some spots it is very rich such as from 4-5k rpm and then again from 5500-6500 rpm the afr is in the 9s there. and the map sensor pickup for the haltech was in bad location so the signal wasnt smooth, thats why the curve looks choppy. the car was supposed to rev higher but it ran out of injector duty cycle due to low fuel pressure because of the busted fpr.
after those things are taken care of and the car is better tuned you will see a better powerband.
this was a 4th gear pull. you think that turbo doesnt spool fast enouf? go find me another car that has 105 hp at 3k rpm with a t04s. and this is all with the s4 t2 low compression rotors.
