Baseline runs are generally between 40 and 80 bucks depending on the shop. Sometimes they wanna pay that 45,000.00 dyno off real quick, so you take it in the back side.
Custom tuning through a reputable tuner whom you build a rapour with and actually become trust worthy of is priceless. It makes a long drive become reasonable and it makes the cost something not so worried about even when it exceeds 400 bones.
1st time customer custom tunes locally here are generally between 425 and 475 nearly everywhere. If you make changes and need a retune, it's common that that will be 175 to 200 as a repeat customer.
If my tuner charged me 300 a crack for retunes (he doesn't but if he did), I'd pay it, because the relationship is that trustworthy.
