hi, i have an ap2 2005. stock form it had 202whp without the cat (in Puerto Rico). i put an AEM V2 and got 203whp. then a MEGAN header and got 204whp. finally i installed a j's N1 single 63mm and got 205whp. looking at that weird behavior i noticed that the A/F ratio stayed at 12.4 all the way always. the ecu is learning from mods and adjusting to stay at the same A/F. if i put an APEX, will the ecu learn form it and adjust it again???? and what A/F can i leave it safe will tuning??

any help will be apreciated!!!!

 

Did you put these items on while you were at the tuning shop between dyno runs? If you did, the ecu most likely did not have time to learn your new mods.

nop. the items were put at different times!!! reseting the ecu will do anything??

 

Yeah I would try that. Your mods should be giving you significantly more power than that.

 

any other suggestion??? beside apex, emanage or ems?? why so little gains?

 

You should definitely get an Apexi Neo or similar device. This would greatly help bring out the potential of your mods.
