Just wanted to pop in and let you guys know that I have an appointment with UPREV next week for inspection/troubleshooting. For some reason, I only have the P1421 code on my low boost map and boost control setting. If I run my high boost tune and boost control setting, no P1421. Strange..........
Props to Sam for popping in and offering solutions to Cosmo's issue.
