COBB V3 boost levels?

sy2767 · 05-26-2014, 11:39 PM

I guess what im asking is how does boost increase in relation to what tune your running? For example....
STG 1 Sport= Boost psi ?
STG 1 Aggressive=Boost psi?
STG 2 Sport= Boost psi?
and so on...?

The reason for my question is i tried Stg 2 aggressive ( i run 94 octane) and all the AP is showing is 11-12 PSI, is this what it should be? When i set up my AP i set it up as my car being bone stock, does the AP take this into consideration somehow in relation to what it allows the tune to do?

You'll need DPs to run stage 2...

But regardless...that's low. I think I was getting 16-17 peak on stage 1 aggressive with FMIC

I am aware of what parts are needed for various tunes, just want to know what boost levels should be for each one.

Stage 1+fmic makes more boost than regular stage 2. Idk what the numbers are exactly

I have stage 1 aggressive and I hit a peak boost of about 15, but it's really not the peak boost you should be thinking of, it's the sustained boost. The higher tune you go with the longer the sustained boost will be. When I had stage 1 + aggressive tune in my previous car, I would see a peak boost of about 18. You will see the ceiling stop at about here with all the OTS COBB maps, the difference you will see however is sustained boost, which is obviously longer with the stage 2 maps because of the downpipes allowing the turbos to spin more freely (eliminating back pressure allows the turbos to not get "clogged up" and can run higher boost levels for longer periods of time)

If you are just wanting to know about peak boost however, the stage 1 drive and sport hit around 11-12 I believe, and the aggressive hits around 15. When you get to the fmic tunes, they start to look pretty similar. The stage 1 + aggressive tunes are similar to the stage 2 + aggressive tunes and both these tunes are superior to the sport and drive maps.
