I'm installing my PFI turbo on my 95 soon,so I ran a compression test and here's the #'s on a 110K mile,#1 seem to be low.What do your think?Is it still OK to boost with a good dyno tune on 6-8psi?I already got an xtra motor laying around my friend's shop,LOL!Going to test the compression again tommorow,cause I just clean the intake plenum and injector with the B&G product.Thanx for your help,any advise what to look out to or to watch for?

#1=175 the one in the front to the pass side.
#2=192
#3=192
#4=203
#5=196
#6=202

 

202 or 302 for #6? if its really 302 then something is definately wrong, probably with the way you read the gauge lol.

 

The difference from cylinder to cylinder is what you wanna look for. The more of a number difference the worse. #5 and #6 are really bad if thats what the guage really read. #1 and #2 are kinda bad too but not as bad

Sorry my sleepy hand type the 3 instead of 2.

Already edited it.
