Finally someone that gets it! Freaking people think you need a duramax to tow a lawn tractor around these days it seems like. However the lift isn't helping you for towing but it sounds like you know this. It would ride better in its stock form obviously.

Photobucket wouldn't work yesterday. 5100s in all four corners, and 1inch over stock rear block added

Its 5 bolts to take the shock assembly out in the front, its not too bad. Time consuming part is swapping the springs over. We just used a Napa spring compressor.

Little over a week to get my 5100 fronts to MN from Las Vegas, and yes tracking numbers were supplied. I ordered a 2inch rear block as well and they must of had to make it cause I don't have it yet.

You need someone with hptuners or efilive. I suggest pulling the computer out and mailing it to Cjtunes.com aka Carl T or finding a local competent tuner in your area. They will be able to flash your computer for the fuel composition sensor you installed and it will function correctly.

So if the truck is a "flex fuel truck" then why didn't it have the sensor already? That indicates that it is not setup for flex fuel in my opinion. If your tech is a GM service technician I would take that with a grain of salt and do your own homework on it. You could certainly be right, but it I'd verify that with a tuner that uses an aftermarket tool such as HP tuners.

I would completely advise against running e85 in your truck until you get the ECU tuned.

Do you not need a tune to turn on the e85 capability? I feel like just adding the sensor would not do anything since you aren't telling the computer to adjust timing/spark for additional octane . http://www.gm-trucks.com/forums/topic/180793-flex-fuel-conversion-everything-you-need-to-know/?do=findComment&comment=1728414 It is laid out in the thread above. Carl T is the local GM tuner in MN that I personal use from my race car, and explains that the you need to enable the sensor in the ECU.
