So as stated when I get a lead foot for a few seconds and do a pull, the boost gauge will read like .04 then .06 then back to .04 then to .06 while I'm keeping my foot in the same place on the petal. What can this be? It only does it for like a min or so, or until I let off the gas and then back on it at cruising speed. It also seems to only do it on the highway in 5th gear at around 70-80 MPH.

BTW, Car is 2jzgte - stock twins - R154 - I have DM IC and IC pipes.

Any piggybacks on the car? Does it buck when you are doing this? If so, how is the TPS?

No Piggybacks. No bucking. TPS should be fine, I'll check it when i get home, only thing that stands out is the throttle cable is a tad bit loose, but I wouldn't figure this to be the cause of it.
