just wondering what the max boost (or recommened psi) i should run on my 91 GQ4.2TD?? it also has no intercooler and done 350k!

Between 10 to 12 should be a good all rounder safe boost mate.

I know they will run them up as high as 20psi but thats not without a few expensive upgrades

no worries man, im only running 7psi atm for round town driving, and want to turn it up when go off the black stuff, and turning it up to 10-12psi will def. make a diff. cheers buddy!!

If you crank it up to say 10pis & leave it there you'll find it performs well in both environments & will give you better drivebility & fuel economy as well.
