fuel press

[crazygn]

Does any one run a joe L 93 chip, where do you have your fuel press set, with the ta54 at 20psi the fuel press was set at 37psi with the vac line off and reading 790's in 3rd gear wot. I up the press to 40-41 and it spooled slower and when i let off the gas it would leave a little backfire. Does 37psi with the vac off sound a little low for 50lb injectors and and ta54 set at 20psi.

i will find the problem with this pig or start a new set up and just start over.

Joe Lubrant's chips are usually set up for about 41-42# line off...

If you are getting backfire when you let off the gas, then cam timing isn't right...Something is definately not right there...You should not be getting any backfire, ever...That is not normal...
