    That is a nice setup. Wonder if those are King coil-overs.

    275/65-20, What Size Level Will I Need?

    275/65/20 is 34.07 inches in diameter. IMO that will not fit without a ~4" lift. FYI I run 285/65/18, which is 32.59 inches, with a level kit and still had to trim ~2 inches from the bottom from valence (Z71 Tahoe).

    Airaid Jr installed. Question about resetting computer

    Wow... Ram airflow is different than just providing a larger opening (before a restriction like the MAF which you agreed was limiting flow) or reducing frictional losses. Dynos were the ones referenced and I have not seen any data such as dynos that you have provided. Butt dynos do not count...

    AirRaid JR - disappointment

    I wonder if the rattling sound is a sign of running lean. Can you describe the sound a little more?

    Airaid Jr installed. Question about resetting computer

    Restriction is not only the diameter but also the frictional resistance due to bends, corrugated piping, and surface roughness. Yes only so much air flow through the MAF is possible which is why any changes before the MAF will have minimal improvements as shown in the dyno testing results.

    Bilstein and CCM Level

    You can do it, but your front suspension will not last long. Post some pics of that setup showing the CV angles and inner/outer boots. Also is it 2 or 4WD?

    Airaid Jr installed. Question about resetting computer

    The dynos show the most improvement was gained from changing out the intake piping. That is where the restrictions are, so any upstream changes will have relatively minimal gains. In the end the gains are relatively low. Don't get me wrong, I am all for DIY performance mods and have done...

    FYI for some folks. Black Bear actually took the time to dyno test a few intakes. Here's the link. http://www.tahoeyukonforum.com/forum/showthread.php?t=41254

    Trimming for 285/65/18 tires with 2.5" Level Kit

    You shouldn't have a problem fitting through 6'10" openings.

    Trimming for 285/65/18 tires with 2.5" Level Kit

    Clearance is good at the rear of the front wheel well. No trimming or modification required there. Some trucks may vary though and adjusting the caster should help if you have an issue. I limit parking garages to at least 6'10" which is the opening of my garage. I can fit into 6'8" but it...

    What MPGs are you getting?

    07 Z71 see sig for mods. Recently hand calculation indicates around 15 mpg city and 16 mpg highway @ 65 mph. Winter gas is ~14 mpg city and 15 mpg highway (sometimes less than that). Just pulled a ~3,400 lb camping trailer and got ~12.5 mpg round trip combo highway and rural driving with...

    Shock extenders needed for 1.5"-2" front leveling kit?

    Sounds like the spacer you want to add connects between the strut connection point and the top of the strut. By shock extender, do you mean the front struts or rear shocks (just to clarify)? IMO you do not want to over extend the front struts because it can potentially damage the CVs and other...

    Trimming for 285/65/18 tires with 2.5" Level Kit

    Got a few requests to show the trimming of the front Z71 valence caps needed to fit 285/65/18 on stock wheels with 2.5" front level kit. The picture was from someone else fitting wider tires and the red line was where i trimmed ~2 inches. Pics from the post install. Hope this helps.

    Recs for better MPG pulling trailer?

    Just curious what you mean by the data log appeared you were using regular, but you were actually running premium. That is odd especially when you indicated that you switched to top tier gas stations. Seems like a tuning issue and did you ask any input from your tuner? ---------- Post added...

    Recs for better MPG pulling trailer?

    Hey Jenna, when I had my truck tuned by Justin quite some time ago, I did not think I would be using the tow mode (had him change it to performance mode). We are now towing a 3,600 lb trailer. Do you think there is any benefit changing the button back to tow mode? Thanks in advance.

    Upper ball joint

    Yeah sucks they didn't put a zerk on there. The NBS has 11 zerk fittings which helps maintain equipment.
