I'm running 8 PSI through my procharger on a low-miles (54k) stock bottom-end '98. I keep getting a P1516 code, which I know means i need to at least clean the IMRC plates. I also notice, on occasion, a loss of power that I'm (perhaps naively) attributing to the IMRC issue. Most of the time it's plenty of power but sometimes it just feels weak, like the blower was somehow turned off. Obviously that can't be the case so my current target is IMRC. I'm considering just deleting them since it's not a small amount of time investment to clean them. But then I hear horror stories about low-end torque loss. I don't take this car to the track, nor do I ever intend to. It's just a nice-weather fun car that is in gorgeous condition.
With this level of boost, I don't think it's the pressure holding them shut. With 4.10 gears it's plenty easy to stay above 3250 RPM when I really want to move but I guess my main concern is with cruising. Am I just stuck cleaning these things once a year? I'm hoping that with the blower and the gears, I can get away with deletes... but how much am I going to regret the deletes when I'm just putting around town on a nice day?
