This is for a 4.0l jeep gasser but might be something we can do for boost fooling, any electronics guru's care to look into this one?

 

I had one of those on my XJ Cherokee. I didn't build it myself though as I got it from Turbo City.

 

Well how good did it work?

 

It was very touchy to adjust, which meant it took a while to get to the right voltage. And if it was off by 1V or more than the suggested setting, the truck ran like crap. Once it got calibrated to the 0.2V above stock, the truck seemed to run a bit smoother without stumbling etc. I probably could have played with it a bit more to optimize things.

BTW - I blew out my MAF sensor because I accidently installed it upside down at first.
