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.

The 4.3L V6 in my Chevy Astro van is hot. I use it primarily to tow a small travel trailer and it has always done a satisfactory job but now wow! I can't wait to get it on the dyno to test the hp and torque. A recent two way run of 24 miles (not towing) yeilded a gas mileage inprovement of 3.9 mpg. Needless to say, I am well pleased.
