Hey guys im new to the site. I've had some difficulties with my em1 I cannot seem to figure out I have a b16 with all bolt ons and it has type r cams im having a problem I believe with fuel I have a aftermarket Benin industries fuel rail with stock injectors. The car runs ok when cruising and at idle but everytime i hit vtec the car jerks down then bammm it hit vtec hard but it's a big jerk could it possibly b fuel cutting do to a type r tuned ecu and stock fuel pump? I have a walbro 255 on hand. Should i install that and see if it runs better? Any help would b useful thanks!
