MSRP $329.99 Im asking $175 Shipped
Works on LLT, LFX, LS3 & L99
My main purpose was to disable AFM (active fuel management). I hated that damn bogging noise but it also helped with removing my rev limiter, increasing my max speed and I can put it back to stock within 5 minutes if I took it to the dealer.
This programmer helped me beat alot of cars because I was able to change my shift points. Very easy to use for a beginner.
