Dean_mc88 Posted February 19, 2014 Share Posted February 19, 2014 (edited) Don't know if this is in the right section but here it goes, Had an issue when driving the starlet down the road to test my jam ecu , turns over first time give it a good 15-20 mins to settle in and warm up. Took it down the road and it started boosting correctly so I thought GREAT! Tried giving it a bit of stick in third and it boosted properly but at 4k revs decided to misfire and bog down! I'm talking the loudest bangs I've heard from a car . I do have a slight boost leak maybe this is the problem? Spoke to Keith at zisco who was very helpful and told me to check timing and fix the boost leak , just wondering if anyone els has had this issue and what they did to fix it ? Cheers Edited February 19, 2014 by Dean_mc88 Quote Link to post Share on other sites

Dean_mc88 Posted February 19, 2014 Author Share Posted February 19, 2014 I'm only running 0.8 bar on a hybrid ct9 forged engine etc , sounding stupid but how do I determine gap is it purely torque setting ? Quote Link to post Share on other sites
