Quick 91 TPI question
Stupid quick question but I'm use to working on my 88 L98 with a MAF. I have a 91 Formula with a LB9. On the passenger side of the intake plenum near the rear there is a rectangular box bolted to the side of the plenum. What is this? Thanks for the info.

Yeah, there are some wires coming out of it, I didnt look too closely at it though. MAP sensor makes sense. Thanks for the info.
