Default Cars only peaking 16 and holding at like 14 or 15 with APR1+ I think i should have more Boost!!
2003 A4 1.8t, APR 1+, hyperboost DV
Earlier the car would peak at like 17 or 18 and hold a 15 or 16. I havn't changed anything. Just had my APR software updated to the 2.0 and even still, havn't really noticed any difference. I have a vag-com, but am not to familiar with logging.

Any Suggestions?

Thanks
Joe

Default Although I can agree with AUDIOZ A4, I can probably explain your lower boost......
because it's getting colder, the air is more dense, and less boost is required to get the same air in your combustion chamber to be matched with the appropriately metered fuel. Same power is achieved. This is one of the reasons why turbo'd cars have more fun at december driving events.
