475 boost numbers?

[06dmax]

what are all you guys seeing for boost with a single 475?
i have built motor with 45 over injectors robs tuning the turbo came from trent its a 475 83mm with 1.0ar and my buddy gave me a billet wheel so i put that in and im seeing peak 38 pounds before billet wheel peak 35 pounds just wanted to see what everyone else is seeing?

About 48 stock fuel system.

 

[06dmax]

yeah i dont no why my numbers are still so low havent figured that one out yet

 

[LWATSON]

Have you sent Rob a log?

 

[06dmax]

iv spoke with dustin but he didnt suggest me to send a log ill have to take a log and send it. you think the tunong could be off that much to cause low numbers im new with the efi world still learning it

Is Rob's tuning for the 475? Some of the limiters may need to be adjusted. From what i've read there are things that have to be adjusted with an aftermarket turbo so the ecm doesn't limit fuel or boost. I may be wrong though and i'm sure others who are more knowledgeable will chime in. Rob and Dustin will for sure take care of you.

Definately send a log and have him look at it. My first version of tuning I was building 42 psi, I sent a log and a couple tweeks later its up to 48.

yes both rob and dustin are awesome!! it is tuned for the turbo but ill just have to send him in a log and go from there im prob gonna do twins so itll be gettin changed anyway

I had a friend who hit 55psi with his s475 billet wheel .90 AR

 

[Polaris7x]

Not to hijack but i only see 32 max on my 366 for some reason??

 

[LWATSON]

Is it gated?

 

[othrgrl]

On my built motor with a cast S475 I was seeing about 60 PSI.

My batmo s472 on a stock motor, stock cp3(lbzreg) and .45 overs will pull about 47 constantly and ive seen it spike at 50 before. Pretty sure Chris is seeing high boost out of his 475

Are you using a mechanical boosts gauge?

 

[06dmax]

YEs I am using mechanicall boost gauge and what all should I log to send rob

 

[LWATSON]

Open your scan tool, open PID selection file and there is a generic LBZ imperial pid list that will probably give him what he needs to see.
