My mods are in my sig.I have the hppIII so I could change my shift points fan on and off tire size and stuff like that. I used the search and found a few people that had similar mods and about half of them said a tune with this little of mods really isnt necessary. What do you guys think. I was looking into the madz28 tune. Thanks for the help.

 

Even with just bolt-ons, a mail order tune such as that from Madz28 can add a nice increase in power and driveability. I've had work done by Ion a couple of times now and I have been more then pleased with the results. Probably one of the best bang for the buck mods in my opinion.

 

You don't need, but it should help some. Your call if you want to spend the money now or after some other mods.
