Every time I tune my truck the check engine light comes on and stays on almost all the time. The latest code it throws is P0236 - Turbo Charger Boost sensor Rnage/Performance. It is not the sensor either, because if I "untune" my truck, all the warning lights go away and don't come back. What should I do? Also, my tranny keeps going into limp mode and I only have 50K miles on it. Mostly on hills, but lately at stop light burn outs too. Is there any fix for this or just tranny upgrades?

2002 LB7 with 10" lift and 38" tires, exsaust, K&N filter

here is my forum with some other customers with the same problems:

No one has any answers? How do I just talk to customer service then????

If your getting tranny limps they are just going to happen more frequently, i imagine you limped it from a 5-4 shift or 4-5 shift, a stage 1 transmission kit actually only address that problem by replacing the C3 clutch which is what your likely burning out more and more each time you limp it between those two gears.

I limped my 02 LB7 a few days ago and still have the same tune running but i make sure to lay off the gas around 80km so its easier on the tranny or if hauling for the love of god go down to the 40hp tow tune.

As for the stoplight burnouts those will definitely limp the transmission but I'm not sure if it actually causes damage or if the transmission is just getting confused by the high rpm's and lack of actual speed.
