As far as tuners go I'm still on the hunt. I originally had my car tuned by AMP, but I think it could have been done better in retrospect. Although too their credit, they were very courteous and professional with me so my customer experience was a positive one. I've heard it go both ways with that shop so YMMV. For tuning they used a tail pipe sniffer vs. a wideband plugged into a bung on my exhaust, and the car runs way too rich as it gets in the upper RPMs (10.1-10.5:1) yet somehow manages to make 408rwhp @ only 13 deg of timing. And those numbers are right in line with other E-Force street setups I've read about on other forums so.. who knows?
But because it's running that rich (only at WOT), I've not been dipping in the boost too much until I find the right guy to get it re-tuned a bit. Everyone here seems to swear by PSR and it's still a place I may well go to get things dialed in. I took a visit up there and met Devin, Bill, and Bill to have my tune re-evaluated there. Devin seems like a competent guy and he felt like there was easliy another 20-40 HP to be had just in fuel and timing adjustments. I really enjoyed talking with him and getting his feedback, however, something else about the condition of their equipment just bothered me. Aside from there being engine parts and stuff scattered everywhere (although in their defense they had just started moving into the new shop). Their dyno just seems to be rode hard and put up wet. There was a pickup sensor they couldn't get working so they couldn't plot any torque curves, just HP and AFR and the pigtail on the O2 sensor looked pretty beat up to me. Although the dyno's AFR #'s did move pretty much in lock-step with my own on-board wideband so probably not much to worry about there. It just makes me wonder when the last time was that thing was fully calibrated.
Devin has a great rep around here as a tuner it would seem and after meeting him I'm inclined to trust that notion, but the second part of that statement is I want to know that they guy who I'm trusting to make life or death decisions with my engine is using well maintained and properly calibrated test equipment (the dyno). Maybe I'm putting way too much stock in this however since Devin (I THINK) only uses his dyno to get it in the ballpark but actually uses datalogged street pulls to get the final tweaking done which makes perfect sense if you think about it. Either way, it wasn't the warmest of fuzzies seeing what appeared on the surface to be a worn out dyno with not all the sensors working on it. After all you can go to the most brilliant doctor in the world, but if his stethoscope is busted it's kinda hard to take your vital signs.
FWIW, AMP's dyno wasn't in any better shape and both pulls were within 2 HP of each other and done nearly a year apart so maybe I'm just spewing some BS that I know nothing about but I feel like a shop that shows pride and professionalism in their appearance and maintenance of their equipment is going to carry that over into tuning my car. Attention to detail basically..
Just my .02
