Ive got a 94 12valve 4x4 5spd reg cab long bed with 190600 miles on it. the only thing ive have done to it is straight pipe and air filter. would it hurt anything to turn the pump up with that many miles on the truck?

 

you need an EGT gauge so you don't melt the turbo, but besides that your fine.
Eventually your gonna want more air, but for a decent increase just get an EGT gauge and crawl around here on pump mods.

 

actually you need an egt(pyrometer)gauge to keep from melting your pistons.always remember just cause the gauge reads 1600*don't mean it's ok to maintain that.aluminum melts at 1250*,and that's what your pistons are made of!

 

or you can melt the pistons by putting cardboard in the radiator towing up a grade

 

you have the same truck as me ... mine has 180k on it with everything in my sig and running great, did you tab the KDP?

 

wats cardbhored doin in there brandon?

 

I went to slif my plate up and it already was so i turned my smoke screw forward 3 1/2 turns. didnt seem to help any. need a new lift pump maybe?

 

dude. you NEEEEEEEEEEED an egt gauge!!!

 

what screw is the smoke screw that your talking baout?

 

the plate has been along time before i got the truck and that was in jan. the screw im talking about is the star wheel inside the pump ive also heard it called the smoke screw.
