Hi all, Im pretty sure this has been asked before (sorry to moderators for not being thorough enough), but what sort of kW gains can I expect after getting a tune put in my car while running it on eflex? I'm hearing figures that sound untrue (like 50+kw gains) I have a BF II XR6T with Process West TB relocate, piping, PW front mount, Hi-flowed gt35/40r, PW surge tank and 044 pump, Cold air intake soon to be replaced with a race box - tuned to 350rwkw. ZF is about to be rebuilt and im thinking that converting the engine to e85 full time could be the go to squeeze a few extra kW out of her while its in getting the box done. Feel free to let me know what you guys think....
