The process has been a little slow (Nov 08 to Present), but since I bought my AP from him the tuning came at no additional charge (can't complain there, $300.00 value).
The very first tune I received was a base tune (v4_0_1) that worked fine, but had my AFRs very rich (10.4 at WOT). This past week while I was deployed I received my close to final if not final tune (v4_0_6) from Mr. MM. I flashed my 8 this morning and drove to work and all I can say is WOW!!!
If you own an RX8 and don't have an AP, I highly recommend buying one and if you buy one, buy it from Jeff (mazdamaniac.com). Not only will your 8 get a much needed performance boost, but his tunes also help with rough idle, turning on your fans sooner, oil injectors and more. His tunes are also custom to your 8 and the mods that you have.
Just wanted to spread the word on my success story!
