N55 redline boost on flash tune only

harkes · 08-21-2015, 11:49 PM

Hi

What is the highest boost we have seen proof of at redline with a flash tune regardless of turbo?

My flash tune should deliver 13psi redline but only delivers ~10. I believe a stock N55 is ~5psi.

"my tuner" tells me that they have a flash tune on another car with upgraded turbos delivering 13psi redline... Has other tuners done this too?

I am talking pure flash tuning here - we all know its easy with eg. JB4.

Scrutinizing my collection I have 16 psi, but I have seen 17,4 psi.
about 10 was what I saw on the first flashes. How old is your flash?

My flash is brand new...

So it sound like Steffen has cracked the code..? Without sacrificing safe guards or other "this might prevent your engine from taking a crap" features?

I run without safeguards in order for us to sort out the last bit´s, but some times I wear a helmet

I do get errors from time to time, but that is what we want.

18 was the highest on my car

Bee Pee · 08-22-2015, 02:09 PM

I am only interested in boost @ 7000 rpm. This seems to be the problem for tuners at the moment.

Sound very interesting what Hess Teknik in Denmark can achieve. Krelle Can you tell more about which safe guards are not working / what compromises has been taken?

All safe guards related to the t/c, air temp. , pressure, torque,fuel.
Were both still investigating the programme.
Pressure measured/logged at approx.6500 rpm on the road.

In Russia! But the original file was calibrated in Germany. If you have questions you can email me sonicsonic95@gmail.com I can show you my logfile if interested

ahh my bad. Im glad there is a tuner out there who is trying to get to the bottom of this.

Mystery about sonicsonic 18psi solved. It is 18psi max NOT at redline. Redline is ~11.5psi.
