Default Re: Wastegate actuator problems

your having a huge PTB problem (part throttle boost) the AGP WGA leaves the boost up to the PCM but it is a more aggressive curve. you need to take the boost away from the PCM if you insist on running the AGP. you also should atleast be running the S1. The 41TE (yours) doesn't like the wga, pcm combo. If you want to run a wga look for a S2, it is pcm contorlled and less aggressive.

Moral of the story= if you run the AGP w/ an auto, you need to manage the boost away from the pcm (boost controller etc.) and spend a good amount of time "tuning it". Start at NO preload and go from there. Even at that it will take your PT 100 miles or so to get used to the change. That is why they say we have a "learning PCM"
