I have a JET chip in mine and all it really did was increase throttle response and shift firmness, I bought mine for $75 used and I love it for that price! ALso got a CAI and dual exhaust, definetly woke the truck up. Put high performance coil packs on it as well. Mileage in CITY is around 16 no clue on Highway MPG yet.
