Tuning the GTP Bosch injectors? What is involved in tuning The GTP Bosch 42# injectors with LS1edit to work on a LS1? I assume the GTP's have the same "characteristics" as a stock injector just flow more? All I would need to do is adjust the injector flow rate table to make them work? Any other tables? Anyone have a table they would like to share?

Re: Tuning the GTP Bosch injectors? They're the same injectors run on the World Challenge Cup cars. Same internal design as ls1 inj.No need to adjust offset table. Flow 42# at 58# fuel pressure. I have ported Ls6 heads, LGM headers,ported TB and bigger cam.... I started with this scale far IFR

A bit rich at start up but within boundaries of PCM (+/- 25). HTH Good Luck!

Re: Tuning the GTP Bosch injectors? Wow, This is a fantastic thread 42# Bosch/GM injectors Thanks John. Doesn't it figure ...I answer LS1nitwit's post and I'm the one getting the useful infi - I definitely need to rescale my injectors.
