THROTLE BODY SPACER
I have never used one myself but a friend of mine, (keep in mind it's a different dngine) Said he got one for his 2000 Silverado with a 4.8 V8 and said it helped his gas mileage. I don't remeber if he thought he got more power or not.
I got a 91 c1500 extended cab p/u. I put a Air Raid spacer on it, and did notice better fuel mileage and better torque to tow. I also run full synthetic oil, K&N air filter, and NGK spark plugs and that really improved everything. The reason i use NGK spark plugs is because my brother had a 66 Chevelle that had a small block 406 in it and he kept fowling out other plugs and someone told him to try those and he never replaced another. I also used them in my motorhome and they worked great with the 454 big block.
