I was wondering how many guys have done Mods without doing a pre or post Dyno??

I am going to do some Renntech Mods when the car arrives but the Dealer doesn't have a dyno. Yes, the dealer is installing the Renntech mods.

Won't know the before, only the after when it's taken somewhere else for the after mods dyno.

Before Dyno a big deal? What did you guys do?

Where are you located? I would assume there are dyno shops in the area?

That's another small problem as the Dealer is 240 miles away from me.

Its a good thing to dyno before making changes. If your car is a little to the low side on HP/torque, you can expect it to be on the low side after mods are done, and wise versa. By dyno it before, you know exactly what you have, and what you can expect.

All engines are different, due to manufacturing tolerances, so there are tolerance on output as well.
