1988 gmc 2500 overland build

Who made it? I would love some more power
It was by jet, they don't list them on their web site but they are out there. I saw some on amazon but you might need to confirm it fits your truck. Custom chips are like 350 bucks on a web site I saw.
 
I have this in a 91 K5.
Runs ok but I need to find someone that can tune it [K5 came with laptop and program]
as it seems to run pretty rich.
 
I think when I put my chip in I could notice a little better on the top end when I was going freeway speeds
 
just happened across this thread and went back a few pages. excellent! nice truck for family camping and exploration!

I tried to run a TBI chips stage 1.5-ish something... was different from most of the standard ones Brian had because my truck is a factory Manual trans... did NOT work well for me.

I would have needed a lot of tuning and subsequent chips to get it into the ballpark. getting the Throttle body bored (or putting the plug and play holley on?) could make a bit of a difference
 
I hope the chip helps some with performance
It would be great with better heads.

TBI heads were among GMs worse....

Cool rig though. TBI works good enough for what its designed for.
 
I'm doing everything I can not to void the warranty on my rebuild that was put 1500 miles ago.
 
Truck did great. No problems until 160 miles from home, the ac quit working. Smells like the clutch burnt up on the compressor. I dont know if the compressor locked up, i was too tired to check. The last day of the return trip should have been 9.5hrs but due to a fire they closed hwy 80 right in front of me and after the traffic and reroute it was closer to 14hrs.

Sounds like you had a successful trip any trip where you make it home without needing reapirs on the way is a win. Now your home where repairs will be easier and more relaxed at you own pace with all the tools and all the parts you could need. Also thats odd i have never seen a shock do that either.
