tell me a little more about your 3.25" MAF housing. Is it 3.25" all the way back to the turbo? After playing around with different IWG's, I am now holding 23psi with my 2871, but maxing out my MAF voltage. I'm trying to find the best route to go to correct this while staying with the AP for a tuning solution. I don't want to start with the guess and check MAF scaling if I don't have to! Haha, fixed load cap, now maxed MAF voltage! I hope to see you putting down some big number soon
