Tuning

 

Complete tune performed by myself using HPTuners and the Autometer Wideband. It is currently using a MAF tune with an OL idle however can give an OLSD tune if so desired. I recommend purchasing HPTuners as you will want to tweek to your taste and if you are going to fire off the nitrous, you will need to flash new tunes.

 

 

Extra’s at additional cost:

 

1. Four 16in 2002 aluminum Silverado wheels / center caps / lug nuts with M&H drag radials mounted and balanced.

2. Roughly 50 spark plugs in varying heat range (all NGK).

3. Your next oil change including filter.

4. Two FULL nitrous bottles (will empty if truck is to be shipped).

The truck is always garaged and hasn’t seen rain in years. It saw snow once in 2004. No rust on the body ANYWHERE. No accidents. Frame and undercarriage is well maintained as I painted all exposed metal. Interior is a 9/10 in my opinion only because it isn’t a brand new truck. Seats have been WELL cared for along with the dash and carpet. This is not a show truck however cleans up very nicely and can be confused for one at shows. There is a small nickel sized dent in the rear passenger side door that can be easily removed with a paintless dent removal kit. I have just been lazy as it is barely noticeable. There are a few very minor, almost invisible paint imperfections from typical driving hazards.

 

This is not a typical daily driver as a big cammed, high stall converter truck takes some getting used to. The ideal owner will use this truck as a weekend toy for cruise night and showing off a little. I do not recommend city driving or any type of towing / hauling. A cam and converter change will make this truck a great daily driver if one should desire.

 

The truck did see some track time and turned a best naturally aspirated time of 12.4 @ 105 with open headers and no weight reduction. With a 200ish shot of nitrous, it ran a best of 10.86 @ 128 with open headers and drag radials and some weight reduction. There is a lot of room for improvement.

 

The only needed item for this truck, in my opinion, is a hydroboost brake set-up. With the low vacuum the big cam generates at low RPM, braking is hampered only at low RPM. With good vacuum (higher RPM) the braking is fine.

 

The truck WILL PASS an OBDII plug-in inspection and visual as all EVAP and emissions controls are on and functional with the exception of hollow catalytic converters. I have serious doubts it will pass a sniffer if your state still does this method. The truck just passed PA State Emissions and Safety inspection last month and is good for a year in PA.

 

Asking $27,900 as it sits in the pictures. WITHOUT ALL of the nitrous it is yours for $23,500 FIRM. This will include a brand new FAST 92 intake Title is in hand for a fast transaction.

 

The modifications alone total more than the asking price. You can buy the truck, part it out and slap in a junkyard LQ9/65e and MAKE MONEY.
