I just got my rrm cai installed. I also have an rrm crank pulley. I know people say it's normal to lose a little low end power, but I'm feeling a rather noticeable bog just after the mivec crossover (4000 rpms or so) then it picks up again and pulls good til redline. Is this normal or should I reset the ecu again. No ses light either so

 

reset and make sure you let engine idle for at least 20 mins, drive under 3k staying far away from wot for 15 mins.

if that doesnt work, clean your maf, it may have gotten dirty during install.

 

alright thanks, does it matter if i disconnect the negative or positive terminal when resetting the ecu?

 

remove the negative
