#5159 of 5688 GMC Newbie by dryodt Aug 25, 2005 (7:40 am)
Hey All, I am into my second month of my 2005 GMC ownership experience after 27 years of Toyotas we'll just have to see. Thus far the new truck Crew cab SLT 4x4 Z71 Package has been very satisfying. Took it from Oak Ridge TN to Tupelo MS and it averaged 19.9 MPG with only 1900 miles at origin. It has the 3.42 gears in the rear so that probably explains it. No sonner had I bought it than I aquired a 30" Award tarvel trailer. According to the specs and solid load estimation I am well with in the limits for towing despite the higher ratio in the rear. I got 12.3 towing from Oak Ridge to Atlanta and back a little less. Anyone know about towing in OD with the towing selector on. Manual says go for it but history says 3rd gear only may be the way to go. I think the computer may know better?

#5162 of 5688 Re: a little nervous about perforamance upgrades [m_boise] by stoneg Aug 27, 2005 (7:51 pm)
Replying to: m_boise (Aug 22, 2005 10:03 am) m_Boise, I have been speaking to a couple of aftermarket specialty shops around here, and they all have been telling me to wait until my d-max has at least 10k miles on it before I add the programmer. I am however definatly replacing the 3" exhaust with the 4", as everyone says my mpg's will go up. Now, with the air getting out faster, wouldn't increasing the air in, result in better mpg, more horse power, or ??? Since my truck only has 2,500 miles on it, it looks like I should take the programmer money and spend it on 16"x 10" wheels and replace the stock 16" x 6.5" pizza cutters.

Replying to: stoneg (Aug 21, 2005 6:23 pm) Got it, installed it in about 7 minutes. Looks pretty good. I would give it a 9 out of 10. I think it should either be a little more snug, or should come with a chrome or black trim piece to hide the edges of the insert. It is called the Small Hole-Y by DJ Motorsports. Now my 2500HD D-Max has the sophistication of the Denali front end.
#5164 of 5688 Exhuast systems, whats good. by truitt83 Aug 27, 2005 (10:17 pm)
I just got a 2001 Silverado about 6 months ago, so im new to chevy. Its the 5.3L V8 stepside. I was just wondering what a good exhaust system would be and about how much will it affect my mpg and pocketbook. would it be something that i could do with the right tools. any suggestions would be greatly apreciated.

Replying to: stoneg (Aug 27, 2005 7:51 pm) stoneg-   That was my logic too, so I installed the K&N Air Charger which replaces the entire stock air intake system. I have only had it for a week or so now, and haven't gotten new mpg readings. Do some research, ask around, there are plenty of differing opinions out there. Some say the increased air flow = increased dirt into the engine. This makes sense---but I don't think that they let in more dirt/volume of air---the filtration is equivalent. I didn't see an obvious performance change in my day to day driving after installing it (you may see different changes with the diesel). Check out the previous post I left to see what I noticed. I'm going to give it a chance for a couple thousand miles and decide after that. As for the wider tires, that will look great but is not helping your quest for better mpg. The programmer is something I've also been told to wait on. So, I'm done with upgrades for several thousand miles...just enjoying the ride.
