Well I got the Suburban some goodies for Xmas. Going to try out the TBI Spacer and Injector Spacer. Also picked up an OEM K&N filter for it. Going for a couple more MPG's and a little more HP. Last MPG ck on a road trip was about 11.5

Stay tuned ;)

Get one of the Hypertech salad bowl looking thingies... Supposed to smooth the airflow under the injectors and into the throttle body... One of the magazines did a write up on the TBI Chevys.  That was the best bang for the buck.

Nope. Mine was the 5.7 and it probably had a 700r4.... But I put the air filter in and nothing changed, then I upgraded the computer, that helped in the HP alot and the MPG some. I don't remember the exact numbers though...

Most of the stuff I'm trying is to help the MPG number, this motor stock will pull a house with the 4:10 axle its stuck with. HP increases will just be gravy. I'm hoping to get it up to 14 mpg which is a long shot ;)

Most of the computer mods richin up the fuel mixture which in a kinda sort a way uses more gas, I'm trying the add more air to a all ready rich condition and burn a few less dinosaurs :)

Hypertech now makes an 87 octane computer tweaker... supposed to really wake up the TBI trucks.  But I don't want to kill my 18mpg I get out on the highway...  :D

I saw one in Jeg's for the 89-95 TBI trucks... might just be for the 350's though...  :stupid
