XFI - Map compatibility

[sackracing]

I'd like to swap my stock style MAP with the rubber hose for one of the steel round style with male threads. I see Fast has a 5 bar on their site with adaptor harness, but I was wondering if there was any other MAPs that were compatible. Is the 5 bar too much for our applications?

Thanks

It would be best to use the AEM 3.5 bar map, it will be good to 35 psi, which would be more than enough for the average buick. The 5 bar you will lose some accuracy off boost.

That's what I was looking at on Summit. How do the wiring / plugs adapt?

It should come with the pigtail for it, you can just connect to the existing wiring, you will have to cut your existing 3 bar map plug off,

If you strike out with Summit, we have them in stock with the correct MAP Calibration. You will need to rescale the tune, since the XFI thinks it's a 4 bar
