Stock KR Question

So I have had my 05' GTP for a week now, and finally busted out the scanner/phone. Mind you my car is currently stock with 91k miles on it, I was seeing a max of 2.8* of KR and 10.1# boost. I am just looking for verification that those are common stock numbers. I do plan on throwing in a FWI, plugs, and thermo hopefully this week and will re scan then.View attachment trackLog-2015-Mar-15_10-07-44.pdf
 


headers would likely clear that kr up. your not even at red line yet, so you may have even more kr then what your seeing on your scan.

being stock its pretty normal. and not much to worry about.

10 psi stock is high, should be more like 7-8 psi, unless it's really really cold outside.

It's a GenV, they generally make a little more boost, at least from what I've seen locally; even on the same sized pulley. Cold or not.

I don't get it. Whatevs. 10PSI is a little high, headers or even a downpipe should lower that a notch or two. 8~ at the shift would be a lot more "usual".
 


I thought that was a little high myself, but only having experience with the Gen3 M90 I wasn't sure what the Gen V would do. It was 42* out when I made that pull fyi.

I also got 7to 8 degrees of kr under full load on my stock motor too....well I get about 6 to 7 psi in that range

Even on 91+ octane?

And if it's hot as ballz outside, the boost will drop.

I'd say at temps over 80-90º ambient, the number will be 1 psi lower atleast, because the super heated air will be just that much hotter.
 


Yeah I'm running 91 octane..so I'm looking normal with 6 to 7 psi with it being so hot out

rockers killed off 5, u bend delete killed the rest. still had up to 8 psi no kr. car pulled so much better.

headers and the 3.4 came later.
 


if i drive it like miss daisy, ill pull 16 local. highway is 24 and up. so pretty much the same but slightly better local.
 
I pull 10# of boost at 80°f on a 3.4 pulley on an 04 comp g.

My stock setup I was seeing 8° kr on stock pulley with sd headers and 1.84 rr installed. Tuned it out and the car pulled pretty well for a stock gen v
