i have a p06 converted to p28. its chipped and socketed using chrome. the last cuple days have been spent tuning my car with the best/most experienced tuner in my area. my car ***** and gets with no problems when tuning using his ecu. as soon as he burns a chip for my ecu my car runs pretty shitty. a good 30% power loss and it throws a code 21 (vtec solenoid valve)

anybody have this general problem before? does this sound like a problem with my ecu?

thanks in advance, doug
