Before programming with all the mods in sig, right before, i got 16 or 17 driving hard as hell. This last tank I only got 14 or 15. Whats up with that, isnt programming supposed to lean out the fuel and also get me better mileage, even though Im not worried so much about the gas, I just think that something isnt right. It also didnt feel much faster after I programmed it, and I was thinking that I was missing out on like up to 20 or more hp without programming for my mods.

yeah i'm also getting crappy mileage... it's horrible! if I'm on it I will get 12.5-13.5mpg and then when i try really hard to do good on gas i still only get high 15 and MAYBE a low 16mpg mark. If you find any answers PLEASE let me know!
