i was looking at getting the JET CHIP stage 2 chip for my 85 bird. is this a decent chip has anyone seen any real good hp increases or is it junk? i also want to get the underdrive pulley set jet chip sells they're both fairly cheap does anyone recommend any chips that are better

have the jet stage 2 chip in my 89 formula dont notice much difference

Both Items you have mentioned are WORTHLESS MODS. Read some Posts on those items before deciding to buy them.

start with headers and gears and a posi definitly much more owrth it then the chip

thanks for the feedback i talked to my dad and he said the pulleys would be the only thing but not the chip and he knows his **** so i decided to go with a real good ignition module and coil instead my dad has done this on our old 80 chevy truck 91 suburban and 81 Z28 and was really impressed with them u can actually feel the difference yesterday i did the oil and used royal purple, definately woth the money thats all i'll ever put in her from now on the idle is smoother and u can feel a few extra horses i recommend that stuff

ignition is not worth it on a stock motor start with headers on that lg4 let it beathe

ive heard that the jet chips arent very good, but i have heard that the superchips are alot better. they told me at a speedshop that it called for a 20 hp gain.

Superchip adding 20 additional HP, in your dreams.

If u can, do a custom chip, like getting someone to do it, or better yet buy the hardware to do it yourself. In the end u save money, u learn stuff, and u do what u want to do.

I have a friend who has the hardware, alls i have to do is buy the software, and were set.

Yep, the jet chip is worthless. It only mods the spark curve. It doesn't even turn the fans on early, at least on a 91 Z28.

hey, thats just what the book says, if i was dreaming it would give a hell of alot more that 20 hp.

WHAT ABOUT ED WRIGHT??

Ed Wright has one of the best off the shelf Chips for the price. Its is better then some of the others mention here. I use it in place of the stock 350 GM chip with good results. One reason is that I do not have the time or equipment for the DIY chip burning projects.
