    In theory the pp is slower. It will reach its max rpm in 6th gear quicker than the non pp past 200mph which it would probably never get to. Would like to see which is faster in a mile run because the pp needs to shift before the end of the quarter mile, making it slower trap time and speed. Limiter removed of course

    Yes it definitely was. The only thing they did for me is have their Chevy dealership sell me the “tow away” Ex I have now that was an outer tie rod issue and the wheel not being balanced lol.

    Yeah I realize that but the fact it took 3-4 seconds to accelerate from 50-60 MPH (my brother has a video of it) and saying they drove the same was a joke to me. Gear ratio from the non PP to the PP would have not been that noticeable on a stock vehicle driving around town. Driving one after another was going from a corolla to a race car is what it felt like. But no there was “nothing” wrong with it according to their techs.

    I drove 2 Explorers with the same issue of feeling like it was NA. Both had the rear turbo replaced too so I’m inclined to believe something wasn’t done right.

    Yea I know how it feels, I've done many dumb things with my sho to make the boost not work. I capped off the noise maker before and when that cap flys off there's like no boost and I guess it just feels like a normal duratech but also sounds alot different. And also feels like a corolla

    That can be a big big deal at 90. All the best to her.

    Ain't no theory to it. The PP has always been slower than the nonPP in acceleration and top speed. It's simple mechanics and if you know about actual performance cars, you know how they design for 0-60 and for powerband from gear to gear.

    Simply put they named this incorrectly because calling it a FLEET USE PACKAGE doesn't sound as good or sell as many.

    Now....you can change all of this because both vehicles share almost all parts and can be swapped easily to change either to the other.

    To give an update, everything is bolted together and working well (so far). My updated tune was for catless downpipes as well as a 170 tstat.

    I didn’t realize how much was going to ooze out but I did a damn good job saturating my floor and engine bay with some coolant!

    Only took it down the road briefly but I can definitely notice the turbos spooling quicker and having a decent of amount of more power. I also noticed how much louder the turbos are too, not sure if it’s due to the VTA BOV mod I did paired with 2 filters. I only have an AEM drop in filter too.

    So the front turbo I was unlucky that the stud that snapped was the worst one to access to drill out while on car. On the contrary, I was lucky because that stud was the only one that actually went all the way through where I could drill a hole through. I ended up using an M6 12.9 socket cap screw tightened it down with a nut on the back side. I’m going to try to use soap and water and put it on the housing on a cold start to see if there is any sort of leak.

    Thanks everyone for your help and input, it’s good to have a community that’s this involved and responsive!

    Back when I still had my GTO and exhausted broke off when I was having a larger exhaust installed. The exhaust shop that was working on my car could not remove the stud from the manifold. In order to get around the problem they used a stud replacement that was shaped like a small clamp. It fit over the protruding stud remnant on the back side of the exhaust manifold and fed into the vacant stud portion and clamped down on the exhaust pipe flange. don't know if they still make these but maybe that would be a solution if there is room.
