Hey guys I got a 93 del sol with a b16a swap.. The car came with a USDM p28 ecu.. and it runs the car fine with no check engine lights but kinda cuts out during the vtec. So I got a p30 USDM. and it kinda lags BEFORE vtec..

My question is this: Which ECU is better to run on the motor? Just until I can find a JDM p30 ECU, or get one of mine neptuned..
