hi,
i haven't been posting here for sometime now but i have some good tuning items to share with you guys. i used to have FJO in my car but i found something better and costless and it was sema product of the year. if you have supercharger or turbocharger in your car then this would be nice tuning part.

just click on the link and read it through. it's about half the price of FJO is easier to use and has more functions. with this unit you can get real world air/fuel ratio which is more accurate then chassis dyno.
