Ok so heres my experience w/ the ZPC. I have a CM 5.7 SR5 4WD. I installed the 7" BDS w/ 35x12.5 tires. I had noticed some power loss after the lift. I believed it to be the tires because what power I lost seemed about right for the lift and tires. I did not have any dash lights or experience any other issues as mentioned in this thread while driving. I did all I could to make a dash light or reaction from the trucks computer to happen and I did not observe anything. With the truck being brand new w/ 6k miles on it, I was very nervous about shorting a circuit. Rytesyde gave me great advice and w/ much confidence he convinced me to do the ZPC. I used the paper clip method and followed the "skip to step 4" on the above mentioned PDF. All went well and the ZPC was successful on the first try. I hopped in the drivers seat and immediately noticed the difference w/ nannies doing what nannies do. I then de-nannied the truck and WOW! I spun the 35's w/ WOT from a stand still while turning. Yes it was a turn, but I had to let off. Toyo's aren't cheap! Anyway, I could not do that prior to the ZPC. On the highway I observed better pick up and factory like response from the truck. For anyone that is nervous, trust me I understand. But I would recommend the ZPC. Hope this helps anyone with concern about this topic. Thanks again Rytesyde!

FiveIXZero, did you do anything different from the youtube video that doubleds65 posted earlier in the thread? Thanks for the feedback. I am going to do this today. I just want to make sure I get all the info correct.

Thanks again,

No, thats about it. Key on, insert paper clip 4 times w in 8 sec and key off. Turn key back on and look for traction light to blink.

hmm, subscribed. Now that I've almost leveled my truck, just Kings up front, back is stock, front is about 1/4" lower than back compared to back being way higher before level, and now my a/f ratio goes lean/rich much more than it did. before it would stay almost 14.7/1 nearly perfectly. Now it bounces around a lot more. Full throttle is still around 12/1, but idle and mellow cruise definitely bounces around a lot more. So idk, unless there's another problem, or an exhaust leak that just happened at the same time??

I can't say I've really noticed a power loss or anything. But Idk.

I would definitely start with the ZPC and go from there.

What if you did 3/1 leveling only. Should you still do the ZPC? I have 305/55R20 tires and can't spin tires from stop taking off. Once it goes it still has pep. I figured it was combination of CAI, Exhaust and Larger than stock tires. You stick the clip into the slots while key is in ignition in OFF position then turn to ON position?

Want to do this also but this is only vehicle I got so I do not want to inadvertently fry it.

Follow instructions in the PDF, its on the previous page. Thats all i did and all went well. I believed my power loss to be from other mods as well and i too was freaking out about shorting a circuit. You'll be fine and you'll be glad you did it.

Just make sure you get your positioning right as there are no PIN numbers on the OBD port. fiveIXzero, do you remember was it closer to the drivers side or passengers?

I counted 4 over from the right. (Pass to driver side)
1,2,3 insert on 4
top and bottom

Hmm. So do I just keep it in S mode an hold he gear, or floor it in D an let it downshift?

Roll to 30. Punch it and let it dwn shift. Watch how there is a lag. Then after the calibration it wont lag and be like stock again.
