IMO I would stay away from Martin do some research and you might see why but that's just me
 
I prefer DDM as my old car was tuned by him and in a few weeks my new Gxp is getting tuned by Dave
 
I just had my car tuned on a dyno with HP tuner software, not going for power numbers but AFR numbers I sat at 232/240 with only SOLO street race exhaust, after 30 min of driving and 10+ pulls......Started the day at 16 AFR in full boost WOT, now down to 12.8 AFR at redline WOT....hope this helps.

Also when trying to rich the mixture, adding fuel leaned it, and just adding air richened the mixture.....go figure.....I know its backwards.
Are you the one that was over at EFI getting tuned
 
I got mine done at reinhart automotive off of blanding on last Monday, but they are moving soon
Gotcha I was told there was a yellow Gxp @ Efi last weekend getting tuned
 
Next time you have free time we should meet up
