What is a programmable sport tuned will it really help me increase the performance of my jeep or will it really do anything at all?? Is diablo a good brand??

 

I just had my tuned today (I know this is late for you) with a Diablo at Finish Line Performance and I feel the kick in the pants. Increased the HP by 10 and torque by 20 (With a K and N cold air intake). This was with an 87 tune. (I will try 93 tune after I get a baseline gas mileage) I did have a before and after dyno. I will be doing a followup on this with pics soon so if you have any questions let me know.
