A bit of a pain to install, you have to remove the air-box to get to the ecu. Stage 1 on a stock vehicle, slightly better fuel economy.

I have only used the 87 octane setting on the unit, but definitely noticed a little extra seat of the pants power. Also the transmission shifts are a bit crisper. Haven't checked fuel economy, been having too much fun! You really can't beat the bang for the buck here!
