What sort of improvements did you find? I am considering the upgrade....

I just switched from 1v4 to 1av1 about a week ago. I used regular with the switch ON when I had the 1v4 inserted. Now I use regular with the switch OFF. I don't notice any difference so far with the mileage.. . I get about 20 mpg regularly.. with a lot of country road driving commuting to work, and a moderate amount of city stop-n-go.. . :cool:

Thanks.. :D

P.S. I installed a LAN MOD TCU also at the same time. I do feel a small performance improvement, but it's hard to tell if it's the TCU MOD which causes sportier later shifting.. and/or the chip.. ??? Probably BoTh! :lol:
