did the VE table and some WOT spark advance but there are no gains in Horse power i use the SRT Pages to see if there are gains or no the only gains i got is in the mid rpm range and after shifting now it gives me nearly all the power early not like stock tune but in the high rpm range there are no gains the fuel flow rate got low after i did the Powerenrich i tried to add more air to the engine so it can add more fuel to give more power but nothing happened like if there is something i still have to change for it to add air is there some tables i need to change so the engine could add more air and power ?
Or that's all the engine can produce for the parts i have ?
Parts: Mopar Intake
Corsa Cat-back
HP in SRT Pages is 330-340 HP
The Changes i did so far:
Powerenrich
Total air flow 330 g/s
VE: 100% at high rpm and high ratio
WOT Spark 4 Degrees more
Thanks.
