Are both of the sensors in the GMPP turbo upgrade kit the same Bosch Automotive 0281002845?
I can see on my car that the upper one is but is the lower one the same?
If not then what's the # for the lower upgraded sensor?
Anywhere to get these locally or is Summit, etc online the best way?
Thanks!

This thread has been dead for 3 years, did you:
a) try scrolling through the 610 posts
b) try using the search tool
?

They are MAP or TMAP sensors.

someone on fb answered me with the exact answer.
Thanks anyway.

It's much easier for somebody else to do the scrolling for you.

When I typed "tmap" into the search This came back in about .25 seconds.

How long did FB take?

Had tune done with
H.P. tuner. Automatic 2009
Gm tune, 14.7. 92mph
H.P tune. 13.7. 99 mph
Those times on old Michelin tires
Tonight On MT streets 245 40 18
Times to follow

Was that a stock GM tune or with the GMPP kit?

The 3 Bar sensors were added
1st tune was gm done with laptop
2nd tune was modified
Getting over boost,between 25 and 30 psi
My have happened cause went to different spark plugs
There is a hesitation at 28 lbs boos
Best time last night was 14.09
I was able to run quarter mile low gear

all tunes were done with hp tuner.1st we changed the sensors,then copy of the GM tune
after that did a tune at the track
put new AC Delco plugs back in,still having hesitation at high boost,but not sure if it just night be tire pressure in the street slicks
puting back on computer to se if anything going on in the ecm causing all this.
with these new tires car should be in low 13s
