I have a 99 blazer and its all stock right now besides my lowering. But what are some fairly cheep ways I can get more power out of my 4.3 besides a intake?

 

Besides a cold air system?.. Free flowing exhaust will be the most noticeable, also an engine power tuner. Make sure its got the correct AC Delco plugs in it, Synthetic fluids everywhere, maybe a lower gear ratio in the rear end depending on what you are trying to do.

 

Well I had a buddy who ust to have a blazer to and he got a live tune done on his and said it helped out alot. Just wondering but is it trune that throttle body spacers dont work on the 4.3?

 

That is correct.

 

i have a throttle body spacer on my 4.3 and i noticed some midrange gains in the way it ran i also have a K&N on it.

 

like rriddle3 said, the spacer is useless. swartllk posted up numbers supporting this some wheres. search it up and see for yourself.

As for how to get more power out of her, look into the maintenance stuff a little. tune up, new cap-plugs-rotor-and-wires, MAF clean, EGR valve clean, throttle body clean, seafoam the engine <--- that will clear up the hidden potential of your engine by clearing out all the crap that has built up over time.

x2 on what bandidolenny said, exhaust is the least expensive mod to get more performance (cat back).

CAI, Under drive pulleys, new headers/cat exhaust, Wait4me tune (<--sp?) there is a ton you can do limited only by your wallet, your imagination, and the amount of time you spend searching for neato threads...

Hell someone dropped an LS-6 Covette engine in their Blazer if I remember correctly and had no complaints
