Lost power
 

I have a 95 12v cummins with 109,000 miles. It was all stock when I got it except for mild built auto. I did bhaf, pulled fuel plate, governor spring mod. Ran great for 2 days. Then lost quite a bit of power. I have no boost leak, took afc off and no help and waste gate working like it should. Any suggestions?

Fuel pressure .. put AFC back on .. loosen up star wheel a bit ..

do u have pyro ?

if not .. get one ...

also check turbo and make sure it spins freely ... :tu:

The afc is back on. Only took it off for test. Turbo is smooth and no play. I will hook the fuel gauge back up and see what I got. Pyro and boost gauge coming soon.

The Pyro will tell the story usually .. :w2:

Any advice on what gauge to buy and where to buy it from?

Which ever you like the look of and wherever you can get it the cheapest. I've always had luck with auto meters. But there's glow shift, isspro, etc

Go with auto meter .. I have one and they have replaced the probe once with out cost .. I keep all my receipts ..:tu:

Hooked the fuel pressure gauge up today. Have 22psi at idle and 30psi at 2500rpm no load.

Ok .. that sounds great ....

Next I would start with Timing the IP ... Your timing may have slipped over time and it will cause power loss over time.. :c:

Good air filter, Good flow on the Exhaust as well ? ( have it all checked ) ...

Inspect afc vaccum line for leaks as well
