Vince Riggio Posted March 29, 2016 Share Posted March 29, 2016 (edited) It seems like my 2010 Mack cxu pinnacle sleeper is allot more slower than an other 2010 Mack cxu pinnacle day cab? Why do you guys think? Also the hake break is allot better on the day cab?

TRH Posted March 31, 2016 Share Posted March 31, 2016 Engine rating and type? Specific programming differs thru the maxicruise, econodyne, and maxidyne and their performance is definitely different. We've also had some programming updates that affected the turbo operation during braking but a weak or faulty turbo definitely can cause what you're describing, but the diagnostics are best left to a dealer.

Vince Riggio Posted April 5, 2016 Author Share Posted April 5, 2016 Ok let me put it in a better way... My 2010 pinnacle with the mp7 engine is sluggish meaning my manifold pressure gage is showing low psi Quote Link to comment https://www.bigmacktrucks.com/topic/44576-weak-turbo/#findComment-329589 Share on other sites More sharing options...
