hi guys i am new to this forum and hope you guys are very helpful anything related to EVO.

i bought EVO V 2 weeks ago actually it drives very well and stops good too and overall very pleased with it. but it hesitates like misfires at higher rpm like 4000rpm-or upper range on WOT with boost of 0.9bar or higher. i have already changed fuel filter, and checked all the fuel relays. but it does not go off. therefore i really need your help on this problem.

secondly, what is stock boost for EVO V? is it 1.2bar or something higher. also what bar of boost stock turbo, injector, fuel pump, handle.

lastly, what modification should concern like, less money with more power i already have 3 inch turbo exhaust cold air intake with EBC,

regars, Batbileg B

 

Check plugs.. Could be fouled out..??

 

thank you for your reply, i have never thought about that, it seemed that one of spark plug was not properly tightened, now everything is OK, by the way is it ok to use 95 petrol on 1.2bar all day long, or should i prefer remapping the ECU for downgraded fuel, thank you
