What kind of performance increase both e.t. and HP wise can I expect from a streetable 93 octane safe tune ? This is on an 04' L which is completely stock except for a K & N panel filter and high performance washer fluid.



I am looking at an SCT 9100 flash tuner with a cold performance tune, hot performance tune and a 4lbr tune. I am sure I am gonna end up with a 4lbr sooner or later, but for now am stuck stock.

With a chip alone, " 30 something" if its cool and dry temps. But basically your just laying the ground work for mods to come like you said.
