Noticed the added power instantly. Great product.

This programmer functioned as intended. It boosted horsepower about 10% which raised my average mpg by 21%. Three extra mpg may not seem like much, but when you're averaging 14 it really helps overall.

truck had problems with rpm fluctuation between 40-50 mph. ran the 87 octane tune and it pretty much took care or it. Didn't see a huge hp gain but the tune for the shift points and pressure was well worth it. Should have bought one years ago. Have a 07 Silverado new body style.
