iaintslow Posted March 8, 2008 Share Posted March 8, 2008 I have jdm aristo motor swap( MAP based). Installed greddy bcc today, set it to 4.2v. No more fuel cut but car now hesitating.Where i used to get fuel cut car now feels like i jerk the gas pedal up and down. I cant even spin tires in second gear anymore. I get some smoke and backfire after second turbo kicks in when pedal is floored. Seems to be way better when i dont press it all the way down. Im only running like 15-16lbs Link to comment Share on other sites More sharing options...

Harllequin Posted March 12, 2008 Share Posted March 12, 2008 Mine wouldnt tick over very well at all. Then you could not get it to go past 2k rpm while driving it. Link to comment Share on other sites More sharing options...
