Hi guys: i have a greddy Twin Turbo Set-up with the emanage ultimate, my car runs great with no problem at all, one day when i went to the gas station after 10 minutes when i get the car it cranks, but wont start, i have to wait like ten minutes until the engine gets cool and stasrt perfectly.

i chek the coils, change the spare plugs, change the coolant sensor, i check the coolant, change the thermostat, i check the baterry grounds, when i check the scanner it says "Advanced Overtiming Bank 1" i dont remember the code number and error code PO300 random Misfire. the car runs great..
any suggest apprecciate, thanks.

 

What size injectors you have??

 

632whp on a e-manage?? +1 on injector size.

Sounds like a tune or injector scaling issue. Talk to your tuner.

 

Time for better engine management, better tuner, or both. PM me if you need any help.
