relative4 Posted November 14, 2017 Share Posted November 14, 2017 '05 LGT 5MT, basic stage 2, 89K miles, in Denver. It was hitting about 15 PSI on the OTS tune. I'm going through an e-tune, and the last revision, the first off the base map, showed 14 PSI. I assumed we were working up to 16.5 PSI in steps, but apparently not. The tuner expressed concern that if I don't hit the boost target on the next revision, I need to either upgrade to a 3-port boost controller or check the wastegate flapper to make sure it's not offset and not blocking the hole entirely. So my questions are: 1. Is checking the flapper just a matter of pulling the DP? I had it off recently and my very brief inspection didn't notice anything awry, but I don't kid myself that I would necessarily have caught a problem. Any tips on what to look for? 2. I know nothing about boost controllers. How can a different controller help me to reach boost levels I'm currently not? Thanks! Link to comment Share on other sites More sharing options...
