The ECU adjusts for thin air and increase's AFR's. It must be looking at (IAT's?) another parameter that's still reading fine, and not protecting from high AFR's.
Yeah, I figured it was outside temp related but wanted to just make sure, I am just trying to decide if I should go with TVT injectors or a Kenne Bell Boost-a-pump. I would rather do the injectors but I am unsure if they will fit with the plenums in place. they are a 1/2" taller. As of right now car has delayed shift from 4th-5th probably due to lean condition and pulling timing.
