    Looking to go to 4.88's from 3.73's

    Ok so I got a 6" lift on 35's and as of right now I have stock 3.73 gears. I lost a lot of get up and go with the lift and tires with the stock gear ratio. I'm doing some towing of a camper recently too so I really need to switch them out. In feel like I'm wasting more gas on top of it due to...

    Possible fuel pressure issue?

    Thanks. I got the assembly installed yesterday and I still have my issue with the power at wot from a dead stop. I'm gonna try to check the fuel pressure as soon as I get a chance too. Hopefully that's fixed at least. I'm wondering if the torque management is really that significant to where I'm...

    Possible fuel pressure issue?

    I'm going to take a wild guess and say that's probably the reason why, even when I use higher octane fuel, the motor will still ping at high rpm. I ended up placing the order for a new Delhi fuel pump assembly from amazon. Got it at a great price of $224. I'm sure the labor will cost me more...

    Possible fuel pressure issue?

    One more thing. When I put the bullydog tune on it, it isn't anywhere near as noticeable. It actually runs decently. Why is that?

    Possible fuel pressure issue?

    So do you think that's my main problem with lackluster performance while accelerating? Its just so weird that I lift off the gas and it pulls harder.

    Possible fuel pressure issue?

    Ok I've done some searching and can't find the same issue that I have, so I figured to ask in a post. I have a 2004 Yukon 6.0L . The truck starts no problem, but in the morning my issue is much more prevalent. If its real cold and I give the truck wide open throttle, it really falls on its face...

    Does 2500hd lift kit fit 2500 yukon

    I ended just getting a 6" zone kit on eBay which included the optional Fox 2.0 shocks. Ebay had 8% eBay bucks the other day, so purchasing the kit gave me $100 in eBay bucks. It came out to $1,595 no tax and free shipping. Plus those eBay bucks! I think it was a great deal, so I had to get it. I...

    Does 2500hd lift kit fit 2500 yukon

    What exactly does that mean that it doesn't require a torsion bar drop? I'm also in the market for a lift kit for my 04 Yukon xl 2500. So many to choose from and they vary so much in price and fitment. I even saw a few that says I need to buy a kit to modify the exhaust in order for it to fit.
