Factory boost gauge readings on cts?

ford rules · Jun 9, 2014

Hey guys i was wondering what the factory boost guage will read up to?

I got my 366 in and running and am seing around 30lbs just wondering if im close to maxing the stock sensor out?

Normally around 32-34

Okay thank you!!

Isn't there some upgraded MAP sensors that can handle higher pressures?

Only ones I've seen/used are the GM 2 or 3 bar map sensors. I'll have to do some research on them maybe I could use one instead of buying another guage/sender.

I never went past 31 on my cts. My mechanical gauge would read 40 or so.

Your running a 366?

I'm running a Barder 68mm vgt. Well, trucks down at the moment for a few new goodies. But before I ran the 68mm with 175/stocks and would see 38 on the mechanical rolling into it while the cts would read 31 or so.

Now you're making me want to put my Glow shift gauge back in.... Im maxing out at about 30, with my 6.4 turbo's, I know they will do plenty more than that.

Anyone ever hear of some upgraded MAP sensor that will read higher pressures? Or am I just making crap up in my head...? :wtf:

The GM 3 bar should handle it but I'm not sure about the application if the sensors work the same

It would be nice if we could find a solution to that problem!

So i was watching EBP and boost on the way home tonight EBP was 38 at WOT and boost was 29 im thinking the boost guage is maxing out a 29 since id think that ebp and boost would be a lil closer then that.
Im gonna do some testing on the map sensor this weekend and hopefully figure something out.

You might as well put a gauge on, or add a sender to your cts. A sensor with a higher range isn't going to have the same reference voltage at the same pressure, which would make it inaccurate. The only way to make it work correctly would be changing the factory reference table to match the new sensor. That might be possible through tuning, but you would have to talk to Matt or Eric to confirm.
