I'm looking to do some mods to my car and two routes are in my head and i was wondering if you guys could help me out with a few questions

The first route would be...
Factory Stage two w/ Reflash
CAI
Downpipe

The second route would be...

60# Injectors
2.9 Pulley
GM Shortened Belt
2 or 1 Step Colder NGK Plugs
CAI
Downpipe

My questions are these
1) would route two be worth it?
2) would i run into any problems with route two
3) what would i do about a Reflash/Tune if i was to go route two
4) Can anyone recommend a good CAI?

Thanks in advnace!

 

well what i did was get the stage two and im swapping to the 2.9 pulley the gm tune will work with it but yes route 2 would be worth in IMO and i have K&N it fit real nice but i think most people hear have injen (dont have to oil filter) oh and no you wont run into problems but i think you should get full exhaust not just down pipe

 

1. worth it if your not worried about warranty
2. no just make sure you have someone you can rely on for a tune or a fix
3.you can always get a tune if you add a smaller pulley
4. injen, but to be honest the airbox mod will if u the same gains maybe 1 less hp and is 200 dollars cheaper
