Well i finally got my truck dyno tuned today. For some reason i was unable to get the chart up so heres a link to the chart. The truck was dynoed with the mods below. I was expecting to be in the 400/500 club, but was not even close for some reason? Do these #'s look right for these mods? The truck is a 2002 by the way. Could it be the dyno? Thanks in advance guys.

i blame it on that **** water you call gas.

 

you got it. CA gas is just the worst. Do you ping at all Jubelands? My prime ping area is in overdrive @ low rpm and anything above 2PSI. My truck is a f'in joke. Byron couldnt tune it and he said I was running out of fuel. So I upgraded my pumps and still havent been back but I was only running 15lbs of boost and I KNOW the stock L system can handle that. Its got to be something with my computer. Anyway, I am really interested if you ping with byrons tune. I plan on going back to APEX to try another tune. But in the mean time, Im just mixing in some 100 octane to get rid of the pinging. Oh, and those numbers are a little low but like philosophico said the gas sucks and that is why your truck cannot be tuned to full potential.

 

Your truck sounds almost like mine was. It would ping whenever i would go into boost in overdrive just like yours, but now it doesnt ping at all. It sems to run pretty strong but i was just a little thrown off by the numbers i saw, i was expecting them to be a little higher.

Byron even went with me for a ride to check for pinging and there was none at all. Why wasnt he able to tune yours? You must be putting out a whole lot of power to be running out of fuel.

 

you'd of thought those mods would ahve put you to the 400/500 land... the dyno correction you have off?

 

PInging is really bad on these motors, Get a real Cali tune call Danny Swanson your truck will thank you!

 

you also seem to be crossing a little late. looks like 5300 rpm's

 

With the same scale on both hp and torque, they should cross at almost 5300 rpm's...5252 to be exact. All looks well from that standpoint. But about 40 horse and 40 ft.-lb.'s too low.

 

I take that back. Truck was pinging like mad today on the freeway. I am so F'ing pissed.

 

Based on the bumps in your chart, I would say you have too much timing for the gas you are using.

It's the gas. I put about 3-4 degrees timing less in CA pump gas programs than our normal programs. Some trucks just don't take the 6lb well with that fuel. I can usually get the tune nice, but sometimes it takes a few reburns, every truck is different, and the CA gas trucks are the most finicky. If you had a race fuel tune with some 100 octane, you'd easily make over 400.
