I look forward to hearing for folks about some issue with a TBI with regards to High idle in park. I have the ability to data log with Tunerpro RT and trouble shoot but no why to burn or modify chips. The truck is an 1983 K10 that started its life with a 6.2 Diesel and was nicely converted to a TBI.... I'm guessing this is not the correct area to get into details but rather a Intro! Thanks in advance to all that will jump in and provide there input. Thanks, Jason
