Sorry for the momentary hijacking, is a brick style 3 bar MAP sensor still the way to go for the gen 3 guys (03 silverado) or convert to ls9 map sensor? My version of hptuners offers me a 3 bar OS. Theres a lot of outdated info out there now and I'm a bit confused.

 

 

just started mine up with the zr1 map sensor, plugged right in (2012) , just input the linear and offset values and everything good.

 

I know this has been kinda murkey on this post, but can someone give me a solid answer. I have a 2009 Sierra Denali with the 6.2L and I purchased the GM 12592525 2.5-3Bar map sensor for my Whipple. What pigtail part number do I need to do a plug and play without swapping any pins?

Thanks

 

I have no idea why my text was that big it wouldn't let me change the size
