Sup guys! I'm broke and trying to talk myself into just biting the bullet and get the car tuned. I searched for a while and couldn't find the answer, so here I am. Any idea how much a tune, jms voltage booster, zr1 tb, flexfuel, rotofab with velossatech, and secondary cat delete would make on 91 and on e85? Am I even going to notice it without e85? I have to drive 3 hours to get ethanol so won't be getting very often. I know this has been asked many times in some form or another but they must be buried deep as I can't find them. Car dynod up in Vegas at ls fest 2 years ago at 538 hp. I dont think there are anymore cheap mods I could do before a tune besides swapping pulleys, but its too hot here and constantly running 91.
