Attached are our first version of the Stage 1 tune on 98RON. WHP/WNM and crank HP/NM
All measurements are done in AWD mode

Dip down low is a throttle closure that we will fix next time on dyno

Very nice
Jb4 made the same gain but your draph is looking better

They did 7.3 sec 60-130 mph

Do you have some acceleration info?
Do you cracked the ecu or you flash the car true obd?

Cool, the issue with a piggyback tune is that the AFR is high 14. And those runs were on E85 mixes.


It's a real flash tune, ECUs unlocked on bench without opening. Rest is done by OBD

No acceleration times yet as it's over 40C ambient there. Hopefully soon the temp drops to 20-25C. Should do 5.9-6.2 seconds 100-200km/h

We will try racegas too, I'm sure it can do 750whp easily

Sounds amazing
Just 0.25 bar over stock to gain that power and do that time
Is crazy

What are the mods on the 636 rwhp graph ?

Have you tried a 2wd dyno. I’ve read conflicting reports that you can not dyno in 2wd as the transfer case can force the front wheels to operate ?

Do you think you could dyno test it on a 2wd dyno even though the power reading would be down 10rwhp ?

They are not working on this. We are the only one in the world with access to the ecu.

All others just buy files of Homepages and claim they are tuners lol
