[QUOTE="01silverstang, post: 16663324, member: 21743"] Just wanted to come back for a follow up post. I spent Tuesday night going through all the piping, the water was limited to the low spots of pipe on each side of the intercooler. The intercooler had water droplets in it and was damp, but no significant water. I cleaned everything out, and ran a hair dryer through the intercooler to dry it and then went though all the coupler to make sure they were secure and clamped down tight. I also cut out the old MAF harness/connector and soldered in the new one, and clocked the MAF housing away from the front tire. Wednesday I put the bumper back on and called it a night. Thursday I took it for a drive to determine if this solved my issue, or if more data logging and potentially a new VMP 5000 MAF would be on order. I'm happy to report the call pulls hard and smooth with no cutout. AFR goes down to 11.3 under WOT, and everything appears to be good to go. While I can't say conclusively since I changed the harness and got rid of the water which did the trick, I'm leaning towards the water. My thought is that at part throttle and low load the water just sat in the pipe, but as the piping crossed from vacuum to boost some amount of water was being pulled onto the MAF sensor. The water likely cooled the resistor to the point that it registered as MAXED and this caused the cut out. I will say the idle is way smoother now as well. Thanks to everyone who offered a suggestion, glad I can enjoy my car for the first time since I bought it in January. [/QUOTE]
