Thread: LF - Stock bin file - 2004 Grand Prix GT2 (l26) (non supercharged)

Check the tuning section and bin files at BonnevillePro.com If I have one, it's there.

Thanks Bill - I didn't see a Grand Prix category there in the BIN section.

I found one in a thread on powrtuner site but the skewing is also like my 3800pro bin... just doesn't seem factory - I won't believe they would skew them that differently so I believe I am still searching for a stock bin.

I registered for bonnevillpro and voila Grand Prix section appears in bin file category - and VOILA!! 2004 GP l36 bin file is there

Thanks Bill -


So this is the 2nd "stock" bin file I have got my hands on and it also has a weird cylinder skew... really odd... I just can't wrap my head around the fact why GM did that... unless they figured out some new stuff since 2003 in the NA version motors ... which i doubt..


I pulled up a 2003 L36 file to double check and sure enough.. 100% skew across all cylinders...

this is odd...

Just downloaded 2004 Regal L36 bin and it is skewed 100% on all four cylinders....
