Hi, my problem til today ever since i upgraded to S2 cams & ATP Gt3076R T3 4bolts turbo is whenever i immediate full throttle my AFR drops til max 10afr as shown on my AEM wb which makes my car hard to accelerate.
The only way for me to catapult is to go partial throttle and re-throttle again and again.
Ive since changed back to stock 560cc injectors with the stock latencies & scaling values.
Will it be my cams overlapping problem?
Is there a better way to set my S2 cams?
Im now using latest Synapse recirculate bov and minimal boost leak.

TPS on Full Throttle 96.5%

Boosting 1.45 bars base on WG pressure.
85.5mm pistons with 8.5.1 comp ratio
38mm Turbosmart WG

Other than that, car still runs massively aggressive on the lower end til top end but just cant immediate WOT.

 

That seems like a lot of turbo to still be on stock injectors.

 

Did you get a tune after you put in the S2's?

 

Yes, have been tune and have confirmed that my tune is ok.

The injectors still able to supply for the whp im having...
Reached 90% once awhile.

Is it due to the turbo lag or the sudden surge of air which my 2.0L cant consume fast enough?
(just a guess)

 

Anyone to share or advise?

 

A log would be an excellent start. What gears does this problem play in? First second third fourth fifth or seventh?

 

All gears 211...This is the mystery that i wish to solved all this while....
