Background: B20 Vtec Turbo with Hondata Stage 2 with boost Problem: I engage the throttle slowly and the is hardly any boost (That is obvious). But when I hammer it and it boosts up to around 4-5 psi. The car stutters and then I lay off the gas. Once it does this stuttering, I get a Check engine light 16 (Fuel Injectors) and code 43 (Fuel Supply System). I just shut off the car and restart it then drive is slowly home. I have checked all the pipes and they are all tightly connected. I have also checked all the vacume lines and they seem all good. Do you think it could be that the blow off valve is not adjusted correctly??? I recently had my injectrors cleaned. I used a noid light to each injector and they checked out ok. My fuel pump is coming on and the pressure is all good. I had the main relay re-soldered to rid of possible dry joints. I just changed my O2 sensor. Please help!!!
