tuning

I eventually want to put either a supercharger or a turbocharger on my 2005 4.0I6. I wanted to know if there is anything that I should focus on before doing this upgrade. Also what would be better supercha or turbocharger or both? Any help would be greatly appreciated.

Upon start up of SET sorftware I am recieving an error message saying "Activation failed Error 1653 please contact customer support". Has anyone else ran into this issue? Where you able to get it fixed? I don't run the software that often just when I am trying to fiddle with some of my 00 TJ...

Hey, I know the TJ's aren't the best on fuel but from everything I've read the usual consumption is around 15MPG. I get around 10 MPG... I have 31-inch mud tires, a 2-inch lift, and fully unloaded all the time (1 person fairly light, no seats or anything in the back, 0 luggage). I've noticed...

Hoping someone can help me. I have a 2006 Rubicon with a BoostedTech Eaton M90. It uses a split second FTC-202 with a 7th injector. The issue I am having is that I can’t force it to go into open loop no matter what I do with the HP Tuner. Unless I am at 100% throttle, there is an insane delay...
