    Swapped my rear rotors today and my pulsation is still there. Its sort of a rumble when braking on the off ramp. I swore it was the rears but no change. Could the fronts be rumbling ever so slightly? I can’t feel it in the steering wheel at all.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    No, he is out of Cub Scouts now and has moved on to boy-scouts.

    So, do a log like the one described in the initial tune request?

    Thanks! Being a retuning customer and considering your change to the Free lifetime retune policy, what would be the charge for this service?

    I do have an autocal and can take a log. I have been running E85 for several weeks now but I am not sure I want to log on that since I also run on the 88oct E15 equally as much. Which would you prefer I log?

    The thing I hate the most about how this truck drives is the throttle lag. I wish @BlackBearPerf could tune more of that out for me. I love my tune otherwise.

    With this thing its like the trans needs to downshift two gears when I get back on it and it is just slow to do it. Its not consistent except in a specific intersection under exact circumstances.

    I remembered your fueling issue which was why I suspected that. First thing I did was log the fuel pressure and watch the trims. Everything looked fine. Of course it didn’t act up on me with the scan tool connected tho. I ran two bottles of Techron through it on the last tank and have been...

    Yeah, I realized I took a bigger battery out of it. Had an 800 cca in it. Was thinking of swapping it….

    GeorgeB’s 2013 Suburban LTZ “Fin”

    I was worried this might be the case for me but I consistently refuel at 1/4 tank and almost always put in around 20 gallons. I only ever notice it when I am coasting and then get back on it. It might actually be the trans trying to find the right gear. If I mash the throttle it downshifts and...

    Just ordered a warranty replacement set of rotors for the rear from RockAuto. I have 40k on them and they are warped pretty bad. Going with the same Raybestos coated ones. Hope these are better.

    GeorgeB’s 2013 Suburban LTZ “Fin”

    Noticed an odd behavior. 1/4 tank of fuel Coasting down from 50mph into a right turn with a yield. When I get back on the the throttle I experience a hesitation to accelerate. Once the trans figures out it need to downshift the truck goes as it should. Seems to only happen at or below 1/4...
