94 Gas/HP
 

I see you guys talk about newer trucks a lot but what would you recomend for best gas milage and horse power gain for a 94 silverdaowith the 350.

A mild chip, Throttle body spacer, heads (if they are in your budget), intake or at least a K&N filter, lower temp thermostat and exhaust system. If you do these things and drive normally (not lead foot) you'll increase your mpg. I think your truck has a MAF sensor. Clean the MAF sensor and the throttle body. Keep your truck tuned up, fluids changed and your tires inflated and you should be good to go. These mods I started with on my 91' with a 305. City driving was about the same but there was somewhere between a 1 to 2 mpg increase on the highway before I put heads on it. Lets just put it this way, I would cruise 70-80 (in the hilly areas of Western PA) and it would never downshift meaning better mpg to begin with.

I have flowmaster 1-in-2-out exhaust system already and now im looking at tbs. i see a couple different brands and im not sure if it really makes a difference which one i get because it just looks like a machined block of aluminum.the ones i keep finding are airaid, poweraid, and electronic performance. Also any suggestions on where to get them cheap?

Try summit racing for a transdapt. They run about $47 for your year. And consider true duals. I had true duals on my 93 and it gave about 1-1.5 mpg imprvement.

oh really thats pretty good. i bough a transdapt torque curve this morning from the local speed shop for the same price. i would also like to do the K&N CAI and hypertech chip soon too. well see tho. it all depends on the money.
