I have a 1995 Acura Integra b18b1. T3/t4 turbo with hondata s300 v3 engine management. Recently got the car tuned and after getting car tuned the engine runs as did before (more powerful now) the issue now is that when driving the vehicle the engine is operating as it should. Then when an electrical load (headlights,cooling fan, etc.) is actuated the idle drops and engine starts bogging also instead of -20 vacuum on the boost gauge its showing -17. So far I’ve checked the battery (new) with no electrical load it’s reading 14.6 volts with engine running, when headlights are turned on it’s reading 14.3 volts. This to me seems okay. I checked battery terminals and ground wire for battery, all are tight. Could this issue be due to the tune? Tuner installed new spark plugs (ngk iridium) also put a new main relay in.
