I just recently put a lot of money into my Z, I've made a few posts over the past two weeks for help with specific problems, and I'm extremely paranoid about detonation so I'd like to seek professional help and I was hoping for a good recommendation. I'd prefer to go somewhere where it's not the first time they've seen a Z like mine. I just dropped about 6500$ and the short story on what was done is this. Pulled the motor and replaced the turbos with Z1 GT525's with thier split DP's, tore down the motor and replaced all the seals/gaskets, and a new engine harness. Fixed a bunch of other miscellaneous crap that was neglected by previous owner, installes a Z1 ECU with their Doolz and 2 JWT pop chargers, and a greddy boost controller. I installed a boost guage myself to set it up with help from a few people on here. (Car has exhaust, Greddy IC's, and still on the stock injectors from before this) Now I'm not even sure I have the controller set up right, I dont feel like I'm getting as much power as I should, the idle is rough, the car stalls when you hold the clutch in while driving at speed, and just today I did a hard pull on it in second coming onto the interstate, suddenly the note from the engine changed, it felt like it stopped pulling as hard and I eased off/upshifted. I checked the peak boost on the controller and it was only like 11.4psi, but I couldn't help but wonder, was that detonation? (I told you I'm paranoid). it was also like 95 out today. I put some F'ing flower pots over the air filter's yesterday, I dont think it did a whole lot. So anyway, if you have any advice or input please let me have it, or if you know of a good tuning shop in my area I'd really appreciate that also. I'm not any sort of expert mechanic by a long shot but I feel like it this point the problem has to be something to do with the MAF metering wrong, or a fuel/air mix problem. well something like that combined with the fact that I probly have my boost controller set up wrong.... And sorry if this should be in technical, I started out to just ask for a shop reccomendation, didnt plan on getting into all the rest...
