Had my ECU flashed years ago. Just had my engine re-built with high dome pistons, headers, full exhaust and underdrive pulley. She kicks ***, getting 205 psi. But anyway she's missing (random) in idle. Higher rpms and she's smooth as silk. Not the injectors. Closed the gap on the plugs and went over the engine top to bottom. It's not mechanical. Talked to the guy at technosquare, and naturally he wants the car. Well, that's quite a drive. What I need is a shop in my area (I live in Westchester, but I grew up in NYC) that can dyno me and remap my ECU on the spot. Thanks in advance. ANY suggestions appreciated.
