My cuurent mods for performance are an air intake and a stage 1 pcm from milzy. Thinking of what do for exhaust. I've narrowed it down to a cherrybomb or a Delta 40 with 2.5" piping from the cat back. Any opinions on it? Open to other suggestions to, but see no need for duals on a 3100. Also plan to get a 3.4 throttle body too.

 

A little information about your Monte would help.

If you're going to mod then you should do basic stuff and bigger stuff before the pcm.

 

Just basic bolt-ons, mods were in the first post lol.

 

If that's all you plan on doing, I would look into doing those first and then going with the tune.

What year is your monte?

 

I'm gonna take a guess here and say it's a 98-99 monte ls with a 3100 in it!

 

Bingo, a 99. Its not a tune per say as all it does is change the air/fuel ratio, makes the shift points higher along with removing the governor. Its universal, just for the butt synopsis really lol.
