I currently have a GM Stage 2, with a Nates 2.9, K&N CAI, NGK Plugs.
Besides E/H/DP what mod should i get that will give me alot of power?
Right Now Im pushing on average 18psi in the WINTER. Looking for a mod that will give the amount of power similiar that the stage kit did.

 

get a new boost gauge..18psi seems alot for s2+2.9

the stock one's are known to be off at times..this is my 2nd gauge and its ready bad...its tellin me im boosting 20psi end of 3rd gear

 

I did the same thing tonight. i hit 20psi but its also like 9 degees out. and with the wind its below 0.

 

shouldnt really matter...16 with s2 + 1-2psi with 2.9....should be around 17-18psi...

 

The stage kit is a pretty big increase so if your looking for something similar then i would say a 2.7/60's/tune would be close. Without changing the H/DP/E it's prolly doesn't make much sense to go that route thou .

While cooling mods aren't going to give you power gains like stage 2 , if you don't want to do H/DP/E , then a Heat exchanger or dual pass would be a nice addition.

 

meth and a tune
