im thinking of switching from 4.10's to 4.56's in my 94 m6,,,,anybody running 4.56's????????? also whats that hypertech programmer that autozone sells for the LT1? anybody seen it? is it worth the 300 plus they want for it???????/ thanks

 

They sell the same one as everyone else. I'm not sure you can switch to 4.56's with it though, I thought 4.10's were the highest it went. But, if you don't want to shell out that much cash, they as always available on ebay for half that or less.

 

with the 4.56's is it worth the switch as far as performance? is first gear evan worth using with 4.56's????????????

 

they even make 4.56s for the 10bolt?

teeth would break easy on that i think!

 

What kind of mods do you have? 4.56's are great for mild cars, need a cam to pull around 6500 and u got a sweet gear i ran them with bolt ons and gained minimal amount but fun factor went thro the roof. First gear is about 30-32ish which isnt to bad. Its awesome. id send ya comp to ion b4 buyin a hypertech. Oh and by the way i havent busted a set of richmond 4.56's yet.

 

hard to brake something that dont run
