A friend of mine has a 07 GXP with some bolt on mods and a mail order tune. He wants me to tune his car. Most of my experience with HPT is Jbody's, but I have done my dad's 05 Silverado.
I was looking over his GXP tune. I do not see any VE tables. Are there not any? Are the GXP's strictely MAF?
Also no tables to turn off closed loop??
Any tips would be great.
