I keep getting a check engine light at highway speeds. When i scan it it comes up code po299. Do an advanced scan and the computer is saying its getting 14 lbs of boost at idle and 20 plus at highway speeds? Just replace turbox it was cracked. The boost issue was there before and now after replacing turbo. Replaced map sensor on intake and still having same issue. Anyone able to help?

P0299 is underboost. When you say 14lbs at idle I assume that's zero and you are getting 6PSI at highway. These little turbos can push about 13-14 PSI above barometric pressure of 14psi on an up hill full torque battle.

Im getting the reading from my
snap-on scanner. The torque pro doesnt seem to want to read my turbo. Maybe im not hooking it up right?

Make sure you're reading PSI and not Barr or HG
