I first ordered my CaI with Xcal2 combo with brent, great service, always helps through e mails and phone calls, but i don't know why neither Brent my program wasn´t working in my car, he tried several times and ended up in the same thing, no power from 600 - 3000K rpms. I'm not saying hes a bad tuner or a bad person i just had this strange case. I Ordered a VMP tune and i got it in my mail the next day ! and the car runs absolutelly fantastic, love it.
When i get my CMDP´s ill order a Race tune from Doug and see what hapens ...
You probably will not be disappointed with either of your choices, but you may want to consider what others above are saying, and toss VMP into that mix as well. I have no personal experience with *****, but I have both Brenspeed and VMP tunes. Both are great tunes, no doubt. But the VMP tune I received recently is a fricken TorqueMonster!!! If I did not know better, Iwould swear someone swapped rear gears while I wasn't looking.......And the best I can run here in CA. is 91 Octane......
