I see 1.0 bar as well......ecu, exhaust and evo DVs

 

I can hold 1.0 bar with factory paper air filter element and exhaust on our 91 octane California gas. That's all the boost that Upsolute allows for California gas on their Version 4 for my otherwise stock car, so if you see 1.1 , it's probably boost gauge "artifact" .
I would suggest more frequent oil changes with oiled cotton air filters since the oil gets dirtier much sooner from prior experience with BMC and K&N on previous 911s and Corvette C5.

 

Hi. The statement that using an aftermarket air filter was
associated with dirtier oil sooner, is important. It has always
seemed to me to be a dubious tradeoff between a putative
1-2 hp added, vs. less of a filter. If you're going to tear down
the motor and rebuild it every few months, OK, but if you
want your valves and rings to keep compression for the life
of the car, I'd stay with the OEM filter. Porsche engineers
aren't going to leave free horsepower on the table by designing
or accepting a bottleneck in something so trivial as the air
filter surface area/drag.
There was a thread on oil analysis. I would love for someone
to say they had recorded oil test data with a stock filter and
then an aftermarket one. I'd bet the aftermarket one had more
silica (grit/dirt/grind your motor up) stuff in it.

Who is running Hybrids with the Upsolute, there is one entry?

Thanks...

 

Mansour,
You are the only TT owner on any of the TT boards that has repeatedly complained about the Upsolute chip. Regardless of how many times you post about an isolated incident, I still plan to install an Upsolute next month. Give it a rest.
