well i know for a fact that the MAP sensor i ordered reads 80psi of guage pressure, so unless im missing a sensor, the computer has to be limiting it some how.

Ya must be. I remember Doug mentioning most tuning use a boost fooler or something like that.

Couldn't I do it in the U shaped pipe?

You could. I think the aluminum crossover pipe would hold the sensor and give more room.

Hum, well I will look into to it more later tomorow. I am taking the cab off for some stuff next week so now might be a good time to weld in a bung for this. Kinda want to see what the stock turbos are doing before going tow or high powers.
ok, so i checked it and MAP does max out at 37 for whatever reason, but manifold guage pressure reads all the way to 60 psi, but i dont feel its accurate by what i found on my regulator, it looks to read about 5 psi low @ 60 psi

Is it 5 PSI low across the whole range or just at 60 its off?

K your findings are same as I thought. Guess we could use mgp instead of map.
it gets worse the higher the pressure, like at 35, its 37 ect,
MGP is calculated off the map sensor like i thought it was, it was weird when i would change the settings on the regulator the guage sensor would read zero untill i reset the codes, it didnt like that it wasnt running when i made the changes i think, kept throwing a map/baro correlation code.
But anyway looks like if anyone is shooting for over 60psi of boost then you need a dual sensor set up

Ya I'll need something cause I want 60+psi. Have to figure it out.
ok so the plan is to try and set one up on a truck by the end of the week, if everything goes well im going to order more parts to make it happen but i really want to try it on a truck before i ship them out of the country

That makes sense man. Keep me in the loop

Sounds good.
just got a call from drew tech, they just now shipped the cords out, i think ill have them friday, so that will give me time to set up this local truck and make sure everything works, ill keep everyone posted, hes got mechanical gauges so it will be good to watch both and see how they are working.

I would be totally down... seems like a great idea.

according to the packing slip friday but we will see, im also looking into making a harness that just taps into the factory map sensor and robs the signal off of that and seeing how that works, should save about 40 bucks if i can make it work for the guys that want a dual set up

I understand, but usually when you are expecting something it doesn't show.
cords showed up but im having a hell of a time getting the connector on the map sensor, either they are 50 bucks or they dont stock them, cheapest i found was 10 bucks for one connector, still working on that so it might be awhile and the kits now, or i might have to find a different map sensor to use
