SOunds badass, not much different from last years car except a touch quieter…which is odd since the compression and cam are completely different. > > Quik, thanks for the advice but the software i’m using doesnt quite have the same numbers but I understand what your saying. I plan to keep it safe and try to go up slowly try this for your idling issue. what is the new motor with cam and etc? how much different is it vs a stock 350 vs your 383? take a combination of the two and use that for your idle and part throttle fueling. a Boosted tune isnt that much different then a NA tune untill you see over 105 kpa. Since a NA motor is 0 to 105kpa your tune in that sector shouldnt be much crazier then it would be if the turbos arent on there. once you see over 105kpa then that is when you need to start really playing with timing and fuel one thing youll have to tune around is that style intake your not running. that will take some playing around with since the air coming into the motor isnt how your used to tuning with. --- _[View the full topic](https://forums.speedlife.net/t/orr89roczs-1989-camaro-iroc-z-5-7l/188547)._
