can anyone recommend a dyno tuner around ATL, GA
 

I just bought a 370z from a former technician of mine that has a Stillen supercharger. I dont think he ever took it to get tuned and its now throwing P0131 and P0151 fault codes I'm pretty sure he has just the base tune from Stillen. I called Z1 motorsports and I heard different answers from them as far as price. One guy told me $750 and another guy said they couldnt even do it. Thanks in advance!

Unsure of the software the Z was tuned with/or if it just had the stillen flash.
License is 300 + dyno-tuning on a boosted vehicle.
Speak with Robert or Jon,,,as they can steer you & i got confidence in Jon's ability to get you straight.
If it's got the Stillen water/air intercooler,,,there are upgrades for this.
TopGunz -air to air upgrade ; on the forum offers a kit...but Z1 may have something also.

sorry I should've clarified the previous owner did have a license.

Using the Ecutek "find a tuner" page, shows three master tuners in the Atlanta area -- one in Marietta (Forged Performance), and two in Alpharetta (TopSpeed Black and Rob Tuned). I don't believe any of these shops are exclusively Ecutek, and will tune other systems, too.

It's funny but not unusual that one person at a business can really screw things up.
Saying that,I believe that Z1 will do what you need if you get the right guy to do it.
Make sure that Jon is involved.
I was a regular Z1 customer. A few years ago,they had a new person running their
shop. My car was not done right. The price was awful.
That guy is no longer there. I have not been back since.
Jon is still there. However,as businesses evolve,he may be not directly involved in tuning.
He should be.
Did my car.It was perfect.
