Make sure you load the OEM program, if they try to flash over your custom program, yo umay be buying a new computer.


Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17

I have had this happen in the past with cars. You get the smaller powertrain thinking it will be more fuel efficient only to find it just the opposite.

I have a 06 GT Vert with 14k that has averaged 19.3 city/sub driving and normally pulls 26.6 on the highway. Just did about 700 mikes to the shore and back in the lft lane on 79 MPH with the ice on and got 26.33

I have only minor mods: Brenspeed 93 octane XCT2, BBK intake and straight through PYPES

It still wont compete with the mileage I was getting from my 06 C6 (32 highway)

Too many car's, not enough time.
