hay iam some what new to the diesel performance world. i have a 96 f-250 crewcab shotbed. it has a 7.3 tturbo diesel. so far i put on a intake, deleted the cat and muffler. and have a straight pipe back to the axel. i installed a boost gauge tonight and in hits 20 psi. i had a 99 sd before with the same stuff done and it only hit 14-15 psi. the turbo is extremmy loud. my question is could this truck have a aftermarket turbo already??? it says garrett on the side of it ill get some pics up 2morro. iam not sure what a stock turbo looks like???? any help would be great thanks mike...

Don't quote me on this but I think the older turbo's are louder. Maybe some OBS guys will chime in. It could be an aftermarket turbo, you would have to measure it some how and compare it to stock. Dunno

you may have a downpipe already man, they say it really lets the obs scream compared to that squished snake lookin stock downpipe.

My OBS when you got on it full throttle up a steep hill I would see 22psi stock turbo with an intake and exhaust. The OBS have a wheel similar to the wicked wheel and they def whistle a bit, but nothing like my truck now with the foil delete too.

:ORG welcome:more than likely it's a factory turbo. My last truck was a 97 and I would hit between 20-22psi without a chip or programmer. Get that bad boy chip and see how you like it. I bet you love it!:ORG welcome:
