Yes I use Durametric for data logging and the hand held flasher that you referred to for transferring the map from the email to the ecu.
Leading evidence: 'Use durametric' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace map via the obd2' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

It's all on his web site, I just dropped him an email and agreed a price and I used PayPal.

He too agreed it was running too lean and I opted to go back to a standard 3.8 fuel pressure regulator with EV14 750cc injectors.

Glad you had a good experience, I'll likely use him at some point
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys
After doing some data logging I was concerned that my car was running lean with the 5bar fuel pressure regulator on standard injectors.
My car runs K16/26 turbos with GT2RS coolers, 1 bar Turbosmart wastegates with a 200cell Milltek exhaust. I got in touch, all via email with Markski tuning from Chicago. He too agreed it was running too lean and I opted to go back to a standard 3.8 fuel pressure regulator with EV14 750cc injectors.
Having fitted it all back together we got on to remapping the car, 8/9 tunes later followed by data logging back and forth the car feels fantastic and holds 1.4 bar from 3500 to the redline (well in this cold weather at least).
The point of this post is I've always been sceptical of remote tuning like this but I have to say the attention to detail from Markski tuning in doing this was quite incredible. Totally removing my fears and the car feels so much better than what was in it previously.
If it's something that you're considering don't be put off by the fact he's 3.5k miles away.
Cheers
Darren.
I've been very tempted in the past - he often does Black Friday deals which are worth going for if you're not in a rush (maybe not at this point!)
Glad you had a good experience, I'll likely use him at some point
Did you receive the data logging computer and then send it back? That's the main reason I haven't gone for him - I believe you have to pay 350 for the computer?
Yes I use Durametric for data logging and the hand held flasher that you referred to for transferring the map from the email to the ecu.
Email data logs and a new tune comes back, load into the flasher and then load up to the car. All very simple.
No the flasher stays with you, it locks to your chassis number. You extract your original map and send the content back. The flasher is simply a device that carries the information from your pc to your car and vice versa but it remains yours. I've now got nine different maps with different boost levels including mafless tunes all held on the flasher. Take two minutes to change the map via the OBD2.
What else have you done to your turbo to make it a GT2. I'm interested because I'm doing/done the same thing myself. There was a GT2 fuel tank on eBay a while back, I was tempted, but my fuel system makes use of the saddle tank and space underneath since going 2wd. Got a great deal on the GT2 handbrake and silver clocks though!
