I just got my GXP custom dyno tuned by Doug from East Coast Supercharging in Cream Ridge, NJ. My numbers were 426 RWFT and 423 RWHP. My recently installed mods are in my signature.
Very professional staff, many high end cars being serviced. Mega amount of Corvettes parked out front. I highly recommend them to members on this forum.

Great to hear a review of ECS, I've been curious about them. What brand dyno do they have?

They use a system called Dynapack. They bolt it right onto your hubs. It does not use rollers.

Just curious then, do the rear tires/rims come off for that to happen?

If so, then how does it compensate for the loss of that mass/weight?

I would think the resulting numbers would be a tad high if it doesn't.

My first tune was done on a Dynapack. I believe it compensates for the tires being off.

They remove your rims and bolt directly up to your hubs.

When I did my dyno, there was a bunch of people who had already done other dynos and knew their numbers. They said the dynapack was reading a tad low. Though, anyone can mess with dyno numbers.
