    Leveled Z71 Tahoe

    Here you go :mexsmoke:. Mods as noted in my sig. Great setup: retains stock ride and great offroad. Louder than AT type tires but still quieter than a full MT tire. So far have 34k miles on them and they are wearing great (probably get another 10k with tread still left). You need to run...

    Rough Country 2" Leveling kit with Stock wheels/tires

    Looks higher in the front. Did the kit come with a spacer for the rear coils?

    Rough idle after tb cleaning

    Tech II at the dealer or a mechanic.

    Black Bear Tune on my 2011 5.3L Tahoe

    Yes calculate mpg by hand and do not use non-major oil gas. Also they might have started using the winter blend that would show a loss in mileage.

    bad MAF***slow acceleration

    Yeah the TB spacer is a good paper weight. Hopefully you do not have one of those tornado things...

    Slowwwww Acceleration

    Is it slower with the new intake? Do you have the correct model or is it for the 5.3L?

    Rough idle after tb cleaning

    You need to do the TB reset/calibration. Search this forum, but I recall you need the Tech II device to do this. Did you disconnect the electrical connections to the TB while cleaning?

    Can i remove these from the suspension??

    Just my opinion, but the springs would transmit more vibration/noise into the cabin. Not sure if there would be a mechanical issue.

    08 Z71 with 295/65/18 Goodyear Duratracs

    FYI on another forum, some one put on the Bilstein 5100s and it wasn't as high as the CCM. Also there was less damping than the Z71 struts, so it was less firm/more roll.

    Z71 Tahoe - 2.5"F/1.5"R Level w/ BFG 285/65R18

    Looks good. The tires look smaller that 285s, but it must be the offset of those rims.

    2011 z71

    IMO the lowering kit needs to be removed and stock parts installed. Also was there any cutting/welding that was done to accommodate the lowering kit and were the bump stop cut or extended? Not sure which kit to have on.

    38xxx miles....Hows your suspension feel

    Sounds like it is a perception thing going from lowered suspension and low profile tires to stock. Your last post also indicates you are using Sierra rear shocks that would have a different damping rate than one for the Tahoe. Also which springs/struts did you use?

    Wanted: Good Advice. Brakes Related.

    You need to bed the brakes in properly. Contact the rotor company to find out their recommended bed-in procedure. Before getting new pads, try a very fine grit sand paper to the rotors and pads (I bet they are glazed). The purpose is to expose new material for the bed-in procedure (not taking...

    Sooo..riding clean, suddenly transmission goes out!! 07 Burb

    Fatboy that sucks and I know what you mean regarding kids. Is your rig modded and/or do you tow a lot? InTruck, when you say common, is this for modded rigs? Just curious. I remember the issues you had with your last Tahoe...

    How are your aftermarket brakes holding up?

    I have EBC slotted rotors and EBC Greenstuff pads for about 50k (4 years) with some winter weather. No problems, but I am not sure how much pad is left. Looks like a lot still just looking at them with the wheel on. BTW we camp a lot with a full load and travel up/down steep grades. I...

    6.2 GOAL 475hp/500tq for under $1500

    You are almost there :mexsmoke: and I would like the losses would be more like 15% (or was that based on your stock dyno?). Check the fullsize forum, those guys have some great builds. Those 6.2s are strong with mild mods.

    So what is the difference in 0-60 or 1/4-mile? Also what was the improvement in mpgs?

    major dyno problem help

    ?What were the results? 2 or 4WD dyno? Which gear did you use (is 4th a 1:1)? Edit: saw the other post. Still would like to know which gear you used and see a dyno chart.

    worn out shock bushing?

    Good to hear they figured it out :cheers:. BTW I was not recommending swapping out your $1k spacer kit, just replacing the old stock shocks. Is that right though, the spacer kit cost $1k for parts and labor?

    New tune that is amazing

    That's a big improvement... Keep in mind detonation (ping) may have been addressed by enriching the A/F ratio (adding more fuel) and there was butt dyno perceived increase in performance. An increase of 2.5 mpgs is a lot. Is the COW a dyno tune? Is this based on the DIC or hand calculated...

    3.73 gears are in the esky.

    Sweet that you have the 4l80e! It must have a different over-drive ratio because I am at ~2,500 rpms or less at 80 mph. I also have 285/65/18 size tires though.
