Has anyone tried the hypertech power programer on there 4.3L blazer??? If so what do you think about it????

 

yeah i have one..... its pretty good you can feel diference in power....and your tranny with shift firmer..... i think its a good buy not to mention you can take your speed limiter off which in my book is always a good thing

 

Is this chip good to go for 4x4 2.8L s-10? If so, what else can I do in conjunction with it? I guess tb spacer and headers for right now?

 

its actully not a chip its a comp programmer you plug it in and do what you gotta do to the comp theirs no actual chip change ....and im not sure if you can find one for a 2.8 or have to get a chip for it sorry dude
