I took my 21 Denali L5P to the crew at GDP and they did an awesome job "upgrading" it with a trans tune and SOTF tunes. It been 27k miles now since the work was completed. I'm happy to report that everything is working flawlessly. Thank you so much for great work. I'm also getting some awesome fuel mileage as a result.

An absolute pleasure working with John. I have a 2001 f350. And John's only the second mechanic to work on my truck, and the last one at that. Had my truck a week and reached out 3 times with updates. Price and Quality are on point! All future work/upgrades will be done by grizzli. Thank you!
