Sigmedic Posted May 14, 2016 Report Share Posted May 14, 2016 Good morning, I'm researching through the forums and reviews to help decide what options are most important. I am trying to determine will the PP increase the reliability even if it's primarily a daily driver? Also, to anyone who has a SHO with PP how does the changed gear ratio effect the highway gas mileage? I live in WV and travel a lot for work. Any recommendations or information will be greatly appreciated from must have options to upgrades after purchase. Quote Link to comment Share on other sites More sharing options...
Gjkrisa Posted May 17, 2016 Report Share Posted May 17, 2016 I have the pp at 45 you get 35 every five up you lose five also below 45 you lose I went 400 miles at 70 and got around 24 mpg with some hills in the really hilly area I would go 55-60 averaged 16 during that section car was awesome never downshifted like in previous 12 GMC terrain 4 cyl Sent from my Nexus 6P using Tapatalk Quote Link to comment Share on other sites More sharing options...
Gjkrisa Posted May 17, 2016 Report Share Posted May 17, 2016 I'd rather have pp because I live with snow and love to drift if not for that I'd probably be fine without it just to get the extra 5 mpg I believe someone else has stated Sent from my Nexus 6P using Tapatalk Quote Link to comment Share on other sites More sharing options...
bpd1151 Posted May 17, 2016 Report Share Posted May 17, 2016 (edited) @Sigmedic..... The SHO Ecoboost platform has proven rather stout across the board, PP equipped, or not. The biggest advantage for the 2013 & up PP equipped cars, is that it includes all of the auxiliary coolers not found on the Non-PP cars. Also, the PP equipped cars do come with the 3.16 final gear ratio. Non-PP's are 2.77 No difference at all in speed, etc. once a tune is applied. None whatsoever. Easiest way to tell the differences between a PP version, versus a Non-PP is by peering through the front lower grille opening, and observing the aux tranny cooler (for the PP) & if there is no cooler, than it's a Non-PP. Any other questions, let the community know. Good luck in your quest!

J Persons Posted May 30, 2017 Report Share Posted May 30, 2017 I have a '14 SHO PP with about 16K miles. On a recent trip to Houston it got an overall 28MPG. This was with speed limits up to 75MPH, I may or may not have gone over that somewhat. Around town it gets around 21. I only use 93 octane fuel Quote Link to comment Share on other sites More sharing options...
mjhpadi Posted May 30, 2017 Report Share Posted May 30, 2017 My car doesn't have the PP, and from what I've seen there is very little difference in fuel mileage between the two. It is more how you drive the car, if I drive for mileage with summer fuel I can easily average about 26 mpg in my normal driving in a mountain rich area, on interstates it will do 28-29 mpg. However, with winter fuel the mileage will drop 5-7 mpg ever driving very conservatively. Lastly, if I drive aggressively the mileage will easily drop to 15-17 mpg range depending on how far and how often my right foot gets extended. Just FYI I have kept very detailed fuel records the entire life of my car and I have found one of the worst fuels for mileage is Sunoco, it isn't very high quality fuel and I don't recommend it.
