Best MAP to use for 20 psi
I have a gen 3 4.8 and a gt45 turbo and I may run as high as 20 psi for boost on e85. I know there are some gm MAPs that are 2.5 or 3 bar. I would like to hear from some people about what MAP they use and your experience. I would like to know, part#, did it come with appropriate info for whatever tables I have to alter in efi live for it to be accurate, is it a direct fit on an LS6 manifold, how much did it cost? Thanks in advance! One other concern I have is that I have a factory t56 with about 100k on it. It still shifts perfect and has no problems. I know a t56 isn't usually the week link but could I be ok since I'm using 17 inch DRs and a "750" ftlb rated centerforce clutch? If I put 275 60 15s on the back is it a matter of if or when?

First one was very limited in its reading, would span like 50-70kpa and thats it. Replaced it and now the new one is acting goofy (VE corrections werent being predictable) then it maxed at 105kpa in boost, so no positive pressure reading. Frustrating as hell. Swapping to ZR1 map sensors.

I used the eBay $35 3 bar sensor and the first one lost contact inside the sensor and just died on street. I emailed em and they replaced it for free and it lasted two years and now on my last race it died as soon as it hit 14 psi, started it back up and tried racing again same thing. So I swapped to the duramax 3.3 bar map. Works great so far
