Hey I got my blazer awhile back and I just put in a throttle body spacer and there was a huge improvement, now I'm hooked and was wondering what can I do to boost acceleration, hp, overall performance.

Was thinking of getting a ecu chip but don't know what brands are reputable? Maybe one with an adjustable performance, economy switch?

I'm open to all ideas! but not willing to spend too much since she has 330k, never seen a winter and in immaculate shape.
Thanks for your help !

 

ecu chips... waste of money.

 

port intake,heads,exhaust put an exhaust on

 

Are any ecu chips good? I heard cars are tuned a certain way to accommodate everyone, how could I tune my car the way I would like it to perform? It's all computerized right? So wouldn't a ecu chip help?

 

if you want something that seriously works,do intake and exhaust,then take it to a tune shop and spend the $500+ to have it tuned. you might gain a little using a 200.00 chip,but if you want best bang for the buck have it actually dynod and tuned correctly.

 

then throw a SC on it

 

I'm glad the throttle spacer made an improvement for you. Most guys see little of no improvement after installing them.

There are a few programmers out there, all give you a generic tune that improves performance slightly. A ECM dyno tune has better results, but usually only after other performance upgrades(cam, full exhaust...)
