if yuo are going with a larger TB that will allow more air in and potentially make changes to the AFR then it would be a good idea to reset the PCM to wipe out all LT/ST fuel trim knowledge so it can relearn and adjust as needed with the new TB

 

anyone have an idea on how to can clean it. How many bolts to get the hemi plate off.. so i can look clean it....
step by step would be great....
Thanks
