Recommended Dyno Shops in Ga?

Can anyone recommend a good dyno shop to use in ATL?

I'm about to complete some mods on my e92 328, so I figure I should get a pre and post mod dyno.

LOL!

I guess if you just need a dyno you can go to them... idk if they'll even let you use their dyno if you're not getting any work done by them. Also, I believe their dyno reads a little high. but just my .02

Arthur at Dynolab over in Marietta.

Topspeed won't even let you in the door. They've been slammed from what I can tell. Their dyno definitely reads high btw.

Never heard of a shop in Atlanta with a Dyno that doesn't have a rate to do pulls or rent it out at an hourly rate, especially TopSpeed

Every dyno reads differently and theirs is on par with every single dynojet in Atlanta. This is fact.
E46 M3's do around 295-305 there with headers and their calibration, that's pretty average if anything less optimistic.
One ATL shop that people have tried to prove reads higher is Mainstream, but that's been argued by reputable people claiming the airflow is better there, or the humidity levels were lower etc. etc.

I ended up getting my dyno completed over @ Dynolab last Thursday. Pretty good shop, and Arthur is a nice guy. Even got the opportunity to see a e46 turbo M3 get tuned.

I'll go with a personal experience... they gave me graphs of stock dyno pulls saying I made 291/300 whp/ft-lbs STOCK... definitely high for ANY n54 i've ever heard of stock... then their dyno claimed I made 366/386 whp/ft-lbs on their tune they threw on my car... tune was only running 13-14 psi... so yeah... and lets just say the COBB tune i'm running now (which dyno'd 330/370 whp/ft-lbs at a dynojet I trust) is definitely faster than the TopSpeed tune... track times proves it... so either the dyno reads high or they threw in hidden corrections on my graph to make me happier with purchasing their tune... either way I'm never stepping foot back into that shop lol.

To each there own, as my experience has been totally opposite. I dyno'd my stock N54 got 274.4 and 292 stock and after the tune 320ish and 340ish. Since then I've had them install downpipes and LWFW/Clutch and other small things. Always happy with the work.
Currently I'm around 385/400 running there tune with DP's and FMIC.

I'm glad things are working out for you. They are definitely a capable shop but when the owner literally laughs in your face when you bring proof that their tune is causing serious issues with your car. That's when I take my business elsewhere.


just wondering have you ever datalogged your car with their tune on it?

No, don't have the equipment or the know how. Be glad to let someone data log it and tell me if it is good or bad....
