When I bought this I wasn't expecting a miracle, I drive a Wrangler I expect not to get great gas mileage. That said without changing anything else and just using the 87 tune I saw about a .5-1mpg increase in mileage.
A cost extensive and striking tune up.

I bougt this unit for my stock Grand Chereokee `94. It is easy to install, I only had to pick out the can for the coolant. The electronic and engine is in a better balance and more straight than before. For this price, this is an unbeatable tune up.
