LS9 3 bar MAP on truck intake I bought the LS9 3bar map sensor. Plan to install where the old MAP sensor goes. The LS9 sensor tube is larger than the truck sensor. Should I just drill it slightly and push in or is there a better way?

Ok, so does anybody know if this is actually a 3 bar zr1 map?? Or is it actually a duramax map? I know the duramax would a direct swap, but is more difficult/dirrerent to tune than an actual zr1 3bar map??

The sensor I had was areal LS9 3 bar map, 12592525. I returned it and bought the EFI Source LS1 style 3 bar, http://www.efisource.com/shop/ls1-st...ar-map-sensor/, and it fit right in the truck intake, stock location.

Personally never used the EFIsource version, but if it doesnt last long then its not a good option. Ive used aftermarket 2 bar maps and they are junk right from the get go, so now I purchase OE Acdelco and they have been good everytime. Sure $50 or so a pop hurts but its better than spending $35 a few times or popping the motor due to an inaccurate sensor.
Did you read the post of 3 window above? #10 I believe.
