E40 ECM and MAP Sensor for boost
I currently have a AC Delco 12591290 (LS3 map sensor) and I have a E40 ECM. I used this MAP sensor on my original LS3 intake/head/cam swap on my LS2. I now have a Whipple 2.9 and plan to make about 16-18psi boost max (forged engine now). I understand that the E40 maxes out at 2.5 bar but I need a bolt on style (like the LS3) not clip on style 2.5 bar map sensor for the Whipple. Which one do I use?

12615136 is cheapest option for up to 15psi boost. It's a cobalt SS 2 bar sensor basically.
DSX has 2.5 bar sensors but they're like 2x as expensive
