Not to jack the thread, but is it just me or did prices go way up for used trucks. And the quality go way down in recent years.

The old chevy's are not a bad truck, Be prepared to pay out the hole for fuel tho. My old man had the mate to that truck, and his 6.6 duramax get's twice the fuel mileage old blue got. If you go and look at it make sure to check the cab mounts, cross members, frame etc. Also make sure to check around the windshield and the rocker sills. I see the door is not sitting flush with the cab corner on one side, make sure to check that out...could be something simple as door pins..who knows. If I were to buy that truck, I wouldn't go a penny higher than 1800. But that's me. Good luck to whatever you do!

http://www.autoanything.com/performance-chips/10A50207.aspx There is a list for tuners,programmers etc

Im not sure if your truck is a 5 speed or auto. But I know with a programmer It alters your shift points in your automatic transmission, that's where you really feel the difference. Not saying it wont make a difference for a manual because it also alters fuel and timing..etc, but you probably won't feel as much of a difference as you would a automatic. As for a throttle body spacer, I found the only thing it did for me (08 ranger 4x4 4.0 ) was make the intake louder. Not a big noticeable difference IMO One thing I will recommend if you do get a programmer, go with superchips. They work very well, and are a reasonable price compared to other brands. Also, I would recommend a ultraguage They are about 100 bucks shipped to your door and the gauge plugs into your OBD2 port and it reads everything, it will tell you MPG,Intake temps, distance until empty, it doubles as a scan gauge too, I think there is like 40 some gauges all in one unit. You can even set alarms to say if your water coolant temp got to hot, or intake temps went though the roof etc. I have one on my Cobalt SS|SC and love it. I also used it on my ranger before i smashed it. Sorry for the long post!

Nice looking sonoma!
