Base on GM tech, the stock LNF 2 map sensors can hold a max of 22 Psi and the 3 map can go up to 27 (what ever he meant). That docent mean you cant get 24 on the stokers and 28-29 on the 3 maps.

The tune has nothing to do with it and neither does the amount of boost, that is total BS..
I ran 30psi thru my STOCK map sensors and I STILL have the same sensors on my car today.
Every car Ive seen that keeps blowing them seems to have more blowby then the norm. That oil vapor seems to eat the sensor inside. This is just an observation, I don't KNOW this to be 100% accurate. BUT I keep checking every car and this seems to be the case!

I'm in too, car cruise/playing for 6 hours one day and the map sensor decided to die on me. Almost looks like there's oil in the intake mani but it's not in my intercooler or the intake so no idea. Considering getting a Boomba Evo can, nice little pieces just don't know if it'll help or not.

Very Sorry for the huge mega bump, but when you change the map sensor its self do you have to re-solder or can you take it out like you would say a light in the car cause its clipped in

but if you are putting the bosch (gms1 sensors) in place of the stock ones, they will need to be soldered in for best results...

ok all you need to do is get ahold of new sensors and plug em up and go!!
i got my sensors pretty cheap at performanceautowerks.com and you should already have the pig tails on your car so it'll only be like 80 shipped i think if you need new sensors......

Having read through this thread, I have not found the part number for stock map sensor. Anybody??
Also has anyone had the t-map sensor in the cold pipe being the blown sensor, or is it always the intake manifold map sensor?
I popped a p0107 and I want to know which map sensor to buy. Dealership quoted me 160 bucks for the IM sensor

Yeah, I tried the ac delco number but all the sites would NOT ship to canada, in the end I had the search the gm part number and I think it was off some weird parts site in the states. 80 shipped

A turbocharged car still needs to have the range to read from vacuum up to ambient, which is handled in the first bar or the sensor's range. Then when you go into boost a 2 bar sensor has an additional bar to read pressure which is equal to ~14.5 psi. If the car had a 2.5 bar MAP sensor it could read up to ~21.8 psi boost and a three bar sensor would equal around 29 psi max pressure that the engine controller could read above atmospheric pressure.
