Precision is awesome and John is one hell of a tuner.

Been a customer since 2004.

I gotta go back to get re-tuned @ Precision. My silicone turbo inlet wasnt holding together under boost, so John was unable to complete my tune. Im setting a new appointment as soon as I get my APS hard inlet in the mail.

We also gotta go a little more conservative on my re-tune. 25psi on pump is a way too aggresive for me.

What inlet, what Turbo etc etc?

cpunlamd · 05-26-2008, 05:38 PM

SBR GT35R (stock location)
SBR 3inch silicone inlet

The turbo was making alot of power for the time John had it on the dyno. It sucks that after 5,500rpm the inlet would start to collapse @ WOT. APS hard inlet is on its way.

My STI wasnt on the dyno long enough to tune the car correctly, so I have to stay off boost until I get re-tuned with the APS unit.

As long as timing is conservative, 25-26 psi is not aggressive at all. Put some race gas in and get a 2nd map made

25-26psi on meth is definately conservative. On pump its aggressive, especially if timing was not removed.

Really you think 25psi on pump with a GT35R is aggressive? I mean I am not sure what the GT35R sweet spot is, but for the DOM 3.0R its 25-26psi..

Safety before power is my concern. The sweet spot of a 35R is over 26psi. But a stock EJ25 on 93 pump doesnt agree with over 22psi (especially with stock head studs).

But Im not 100% on that info. Its what I've been reading for the past few years.

Never the less. My latest dyno tune @ Precision put me at 422whp @ 24psi on 93 pump. John and Rich swears it will hold together. And I trust them with my STI. With that said, my STI is a BEAST!
