Boost?

How much boost will our trucks push with an exhaust and a tuner. My autometer guage only reads 35 lbs. Also where do you tap in for this guage. On my 7.3 I teed into the map sensor line, but curious of other options that might be a little cleaner install. Thanks in advance.

It depends widely on the truck and the tune.
Some peoples trucks don't hit that high and some can get about 40.

My truck would hit about 36psi on a tune from Jody@ DP but now it won't hit 28psi on an Innovative tune that pushes the same amount of power (and less smoke even though it
doesn't need as much boost)

You don't want to use the MAP hose. Tap into the intake elbow for the most accurate reading, also if you use the MAP hose over time might cause the needle to flutter on the gauge.

Yes, just drill and tap. It's thick enough to tap. Remove the elbow first so you don't get metal chips in the motor.

You may have a boost leak, either at the IC boots or the flex joints on the up-pipe/y-pipe. Do you have any mods? What year motor? Any work done to the truck recently?

Tuning is going to greatly depend on how much boost, with a SCT SF3 out of the box look for 26-30 PSI. With custom tuning, it can vary, on our 6.0L Powerstroke with IDP tuning we see anywhere from 32-35 PSI, granted that is with 185CC Injectors, AirDogII, & Garrett Powermax. Your 35 PSI should be perfectly fine, if your tuner has you pushing over 35PSI on a stock charger, your WAY WAY outside its effeciency range, JMO.
