but what if he doesn't have any SCT tuners in his area? It can be a hassle getting your car far away to get tuned if you don't have a trailer or funds for a tow.
I prefer SCT but if my local guy was good and he used Diablo then thats what i would go with.
if you all don't mind i would like to get someone to explain these tuners. Do they do the same thing as a chip and can you download custom programs on them or something? If i wanted to get dyno tuned then they could do the tune on the computer and then up load onto a xcal2 and then install????? thanks
