New member... long time reader. I have just rebuilt my 99 mitsubishi eclipse 420a. We have added a super 16g turbo, forged pistons and h beam rods. Stage 2 Brian crower cam (.409 lift). 370 cc injectors and a 12:1 fuel pressure regulator. Full 3 in straight exhaust. I'm beginning to think that the stock ecu is confused.... It runs but its not "happy". Thoughts, ideas and or products to help?
