Hello there Phantom;
Great question, dyno tuning can be the best option when you have some pretty aggressive custom cams, a really rare setup of mods, etc. that make remote tuning rather difficult. In those cases, a lot of shops do recommend, and rightly so, tuning the vehicle on the dyno at their location.
We offer custom tuning but make our tunes custom based on your individual vehicle as well as the mods you have on there. The throttle controller though would be replaced by the tune as we would be adjusting power bands, throttle response and shift points with our custom tune.
The price for ours would be $599.99 and with the purchase price you would get lifetime tuning support (should you add more mods) as well as lifetime customer service. Sometimes having someone pick up the phone when you need help is more valuable than emailing back and forth with a very impersonal representative
Also worth noting, if you picked up another Camaro or GM vehicle down the road that we tune for, we'd also be able to transfer the license of the tuner to that vehicle too.
Please feel free to give us a call if you want any info, we're here for you.
Cheers!
