This is weird.
I have a 996TT and I have the softronic flash on it.
Last year before I put it away for the winter I would hit 1.2 BAR in 1st and 2nd. And now I can't get it past 1.
It is mostly .9.
Why would this happened, I changed batteries since last year.. would this caus anything in the computer??

Boost Leak? Faulty Turbo Bypass Valves?

SWR

are you on the old gas??
that's probably the issue.

I put new divertor valves in last year too....

probably half and half ya...

cold weather? if its really cold, wont your car try to avoid over boost?

the weather is alot cooler so that could be it
