I am converting over to a flex fuel setup and want to start with a stock tune for HPTuners from my exact truck (but the l59 / flex version) to make things as easy as possible. i looked in the hpttuners repository looking for chevrolet tunes with 'flex' as the optional text but only found tahoe tunes for different years. my 03 is DBW and return fuel system so looking for a 03 because its kinda of a hybrid year . 99-02 are DBC and 04+ are returnless so 03 is a mix of both. anyone have a 03 silverado flex 5.3l tune i could download?

thanks
