Dyno Shop or PCMForLess?
 

Which is better? I have 35's and an air intake. I'm looking to gain hp and tune the shift points. Anyone know of a Dyno shop in Illinois?

PCMforless.com does a great job, quick service, easy install. Can't help you with the local inquiry.

Local tuners for the most part will tune on a dyno if you want to pay for that, but it is not necessary. People are way too hung up on numbers, and most have no clue what a dyno peak number really means vs the big picture.

Actually it is better when they ride shotgun with their lap top and tune on the fly. You can experience the variables and test your vehicle to decide where you want to tune it.
