we had a SRT4 over here a few weeks ago that had a turbo and intercooler and we made 423whp on it with race gas.

We charge $100/hour on the dyno. we have street tuned and dyno tuned lots of cars, we wont street tune anymore because of liability and its just not safe and its not as effective.

You need a loaded dyno like a mustang or a dyno dynamics to simulate the full weight of the car. A dynojet basically you are just accelereating against the weight of the two big roller drums which are not even close to the true weight of the car unless its a very light car. tuning on a dynojet works but i'd always put a safety margin in the tune just to be safe especially when tuning on pump gas.

A street tuned car will always be better imo. You drive the car in the real world not the dyno room.
