Few days ago I noticed my check engine light was on, brought home the genisys computer and I read my 237 code. Which means low boost pressure, but when I'm riding around reading the live data I can see up to a 35 psi reading on the scanner. Well this weekend I am towing the racecar to the track and the truck just loses power and won't make over 10 psi. Then it will just get its power back all of a sudden. This happened 2 or 3 times on the way there and back. I don't have a fuel pressure gauge (which I am ordering Monday). Truck has original lp with 47,000 miles. I am open for suggestions as to what my problem is. I am thinking the lp is going and not giving enough fuel which won't allow me to make boost which then sets off the 237 code.


2000 3500 4x4 47,000 miles, stage 2 injectors, boost turned up thats about it.
