Fuel Injectors - MPS


Donating Member
Getting ready to send the fuel injectors to MPS for an ultrasonic cleaning and tuning. Anyone ever use them? GMbusa says they are great to deal with, and I trust Paul. Just looking to see if others have used MPS? Also, going to clean the entire fuel system and replace the filter and spark plugs. Raptor flattens out and stutters at higher RPMs, and when the tubo starts to come in. It's just been sitting too long, so time to get her cleaned out and running right.
