p2263

Same here. I could not find it in the 08 codes. In the 07 codes it's listed as "Turbo/Super Charger System Performance". I'm not sure if it's the same for the 08. I am still running the stock airbox how about you roondog?

i was runnig a custom air intake when i started getting the code so i put my stock air box back on and im still getting it. I noticed that the air filter gauge on the airfilter box was sucked all the way in and i would associated that with the 42pounds of boost i hit the other day. so i reset it and put a little piece of tape over itso it will think its not clogged when it boosts up. the only thing else i did around the time of the code was install the pyro gauge could that be it?

so the SCT R&D tune is still throwing codes?

[Floridayfz450]

I believe they're only throwing codes because of people running stock intakes. I am getting the same code and I too am running a stock intake. I only get the code after getting on it really hard too, once I clear the code, it won't come back unless I really get on it again.

ive tried it with a stock and a cai throws codes both ways.

The P2263 code it still the same as last year..... Here's the description of the code...

P2263 = Turbocharger/Supercharger Boost System Performance

This error occurs when the difference between the gage exhaust pressur and the set point is less than the minimum threshold or greater than the maximum threshold for a predetermined period of time.

Engine speed > 550 rpm
Torque set point > 50 N-m,
ECT > 81 deg C
IAT > -50 deg C
No DPF regeneration request
EP setpoint is stable
Based on a table on N and TQI >5sec


You can DL the list of code for the 2008 6.4L from the following link but it's a 6 meg pdf file so it may take 4-5 minutes for it to load. The codes start on page 90..... http://www.backglass.org/duncan/ps64...que_Charts.pdf
