Engine Surge
I have noticed the last couple of days while driving my truck at a consistant speed (fast or slow) it makes a sound like it is trying to suck air, it also bumbs the boost pressure by a lb or so not a dramatic increase but a constant fluxuation with the guage needle just pinging between say 10-12 for ex. Everything runs okay otherwise tried cleaning air filter removing power chip and it only happens at constent speeds not when speeding up or slowing down. Will be getting an appointment for the shop in the morn, but thought maybe someone would have an idea?? Also no codes thrown just the p0603 and 1000 from removing the program
thanks
