I am new to the diesel world and bought a 05 2500HD with 91K mi. due to cash flow problems. I have been told this motor is good well over 200K :) prompting the purchase. I got sick of you guys blowing buy me on every hill in my gas truck. :cool: The issue is while towing my aprox 13K trailer on even the slightest grade the EGT will almost instantly reach 1200+ :mad: if I dont back out of the throttle. The truck came with Banks 4" cat back & 6 Gun with PDA, that I am only partial to due to the versatility of the PDA for monotering temps rather than guages on the A piller. I have only towed in level 1 or 2 to date with the same result. I have talked to Banks tech RBP etc. and all have different theory's from the 6 gun is faulty, the turbo has an air leak or the injectors are bad. I need help finding a honest resonablly priced teck that can diagnose my problem in or around Orange County California. I hope someone can help? Any advise will be greatly appreciated.
Level 1 on the Banks is stock tune. No power is added at that point. I personally have towed as high as level 4 w/ a 10k trailer and averaged EGT's around the 1300* mark, but I also have the full set-up. I would suggest resetting the parameters on the PDA back to stock just to make sure that the previous owner didn't screw with the settings. It is possible to make adjustments to all the power settings from stock.
Just as a point of reference Level 1-Stock, Level 2-20hp, Level 3-40hp, Level 4-60hp, Level 5-80hp, Level 6-100hp and SL or Speed Loader 120+hp.

I never had to add either a fingerstick or a blocker plate my truck to not code a air flow problem after taking the cat out. The exhaust manufacturer along with other techs claim that only about 10-30 of the LLY diesels would since the cat out. Or perhaps it was addition of the BD exhaust manifold the hp addition of the flashtuner that still make enough back pressure to not set a DTC code.
If your truck came with Federal Emissions rating, then it won't set a code anyway.
