Who's used what , what works and whats worth the $$? Choices are Hypertech, ADS, and JET. They are all about the same $ Will this clear my code 43? Im going to order one with the responses I get from here. I know that they are static sensitive so whats the best procedure for changing one. I need to get my car running its been down for a while , and my friends are ready to torn it in to the next sacrificial bonfire along his exwifes wardrobe ,at our next party . ------------------ 86 t/a w/87 tpi 350 stock minus that nasty cat can with a flow masta. ws6 .Home made slicks.....smokem if ya can!!

your code 43 needs to be looked at, because
the chip probably wont repair the code.
depenent on your mods possibly the 'off-the-shelf'
retail chips wont improve on your different
mods. if its stock then one of those will help.
dont expect wheel stands and 2sec off your 1/4
ets. basically fine tuning from stock tuning
more timing advance, and fuel curve will gig
7-10% gain in hp.
if youve gone as far as cam/compression
change then a custom will be needed because of
the limited 'stock' settings.
