I cannot say for sure. The only other mod I had were the 4:10's and I was able to change this myself on the SCT. I did go with duals, but that did not require a new tune. I suppose if you went NOX or SC, Justin would help you out. He's real easy to work with. I suggest you give him a call.

Almost all tuners will charge you for N/A (CAI) to F/I (supercharge, turbo) tunes. Most other minor mods to the tune can usually be had for free to low cost If you bought the tuner/tune combo from a reputable shop.

Brent (brenspeed) adjusted and re-sent me my three tunes for free when My stock installed tunes had some weird settings installed from the factory. ..
