what are the stock hp. and torque ratings on the 7.3, and with an airfilter,exaust and a chip can you notice a difference in performance and economy

 

Rear wheel stock i would say 190 to 200 HP torque 400 to 425 on a 03 7.3 that is. The fly wheel power in a Automatic is 250HP 525fptorque a 6speed manual is 275HP 550fptorque. Yes if you do air and exchaust up grades, gauges and the right kind of programer, you will see HP and MPG increase, with good driving habit's

 

What JWhitetail said^^^^^^

 

With a fuel system, exhaust, intake, 305 tires and a van turbo/ww i made this:



With the chip on 140 the next run i had: (TS)

 

Here's what I made on 80E, 120R, & 140 Aggressive. Highest numbers were actually on the 120 setting for some reason.

 

Joe I thought you said you made 311?

 

LIAR!!! Now we cant trust him!!!!

 

310.76 rounds up to 311. I didn't feel like cramming tenths & hundredths in my sig. I thought you guys were better at math than that.

 

Mine ran 208 with a 6637 air filter and a muffler delete, then 295 in 80E with 4" exhaust 6637 and a WW...

 

What's the stock boost and what were you guys running when you dyno'ed?

 

stock boost is about 15-18, but with my current mods on my stock setting i can almost hit 26 psi (yes), and the dyno doesnt load the engine down like propelling the truck on the street. Some guys chargers are so large that the restriction of the dyno isnt enough to spool their turbos.

 

Thanks, I'm asking because I don't have the gauges yet and I'm looking at which one to get. Anyone running more than 30-35psi on a regular basis?

 

I can almost peg my gauge, im over 30psi alot but never 35 ya know... If you are looking on major mods, go with a 40 or 60 # gauge, otherwise 35.
