StangHi from my experience is this. If you arent spending big money with him, he doesnt pay attention to your problems. I bought a tuner for my car from there, I started having trouble with detonation and tried calling tons of times and couldnt get him so I just gave up and talked to other's and fixed it myself. Im not saying it was his fault but changing some settings on the tuner made it all better. I feel he should honor all of his customers but im not the only one that had that problem there. His big spending customers get glorified and the ones that buy the smaller stuff doesnt get the same respect. Im not saying its a bad shop because i have seen his work and he does really good work. Im just saying from my very short experience there, i wasnt satisfied. Also the price was outrageous. I paid right around $500 for the hand held tuner and I could have gotten it elsewhere for $100 cheaper easy, and that was local prices.
