No idea why I never read this post. Forum laziness I guess.

I’m going to be picking up a few new tmap sensors since they’re so cheap. Just to confirm, the part number is the same for all L5P’s? I found the part at rock auto but can’t find it on GMparts. I figured I’ll swing by the dealer too and see if they have one in stock. I’m curious to see if I’ll notice any pressure differences on my idash.

Also, it seems most have been happy with the S&B spacer. I’m tempted to order one, but don’t want to risk something going wrong with the engine and the dealer putting the burden of proof on me to prove the spacer didn’t cause the issue, even though legally it’s supposed to be the other way around. Does anyone if the spacer would cause warranty issues? It seems these days everyone is doing everything they can to not pay.
