Yes that's with power down. I enjoyed my original power for a week.

I raced a sport bike the first day I had it tuned, it was even with the bike. No movement. Unfortunately I didn't record it
Nice man... I can't imagine 34psi being my "low boost" mode haha

The methanol bumps my power up. I use straight M1 from VP.

It's a very fun car to drive and surprise those who are supposed to be faster than me lol that's priceless

@l15b7allturbo i am interested in buying a m142 motec and want to gauge the price. Also since you took the whole intake system out and just put the cone right on the inlet of the turbo. What did you do with your maf sensor ? How are you reading air in the system?

Seeing as you didn't get a response ill bump the thread with a guess - speed/density tune using post-intercooler IAT and the MAP

motec is map or throttle based. not AFM.

yep, map is post throttle body, iat can/should be in the manifold as well.

Is there a second MAP sensor post-throttle body? I know from doing the 27WON FMIC that there's a MAP and IAT sensor in the cold pipe before the throttle body.

the sensor in the charge pipe is boost sensor (available boost), its what the factory ecu uses for boost control... the map sensor is in the manifold. The 1.5t has IAT in charge pipe, yes. FK8 has a TMAP sensor, combining the two.

So with motec can you do a 100% VTA blow off valve and adjust for it?

Yes. You don't adjust for it though because the air isn't metered.
