what would the best performance chip be for my 92 bonn. se?

with the mods you have listed, you wouldnt benefit much from a chip. i would suggest some mods that let you move some more air first, then maybe think about a chip, a have the old one re-flashed

im just waiting on my exhaust to come in. what else do i need?

what exactly are you doing with your exhaust?

custom-2.5" single inlet to 2.5" dual outlet to dual flowmasters.

you may want to take a measurement of your exhaust. if you have 2.5, even single, you will NOT out flow it. and the muffler is so far downstream, it will be mostly a sound mod, rather than an actual performance mod. you will benefit from a high flow cat though. and also ported exh manifolds.

your other thread isnt locked, but just to keep your performance questions a little better organized, i will answer in here.

first, to best answer you questions, it woud be necessary to know exactly what YOU want out of modding. what are your goals? you want the fastest na L27? you plan on forced induction? so i will answer based only on what i know already, your mod list in your sig.

1 only cam available will be a custom grind.

2 injectors are not at all necessary at this point. you will however benefit from flowmatching the stock ones. do a search for "FIE"

3 only improvement on the LIM would be to port an oe

4 pistons, why? where are you trying to go with this engine?

i mite eventually go turbo. but im trying to get the most out of the stock engine.
