Hi to all, new to this forum but already have read a lot.
So in short, my Stagea has terrible fuel economy during active city driving (~30 liters per 100km) and has bad reaction on the throttle pedal (not always, though).
What has been done already: new maf, new o2, new knock sensor, whole new timing mechanism including both vtc pulleys and all chains, new injectors, new fuel pump with filter and many others.
Has a bigger intercooler, slightly highflowed turbo, 3 inch cat back, a/t transgo kit and cooler.
No leaks in the intake system, checked. Compression ok.
So the main problem is that the car runs 0.8 boost instead of 1.0 pactically all the time, and sometimes (mainly if started up in cold, but not strictly), first 10 minutes after start and warm up it goes 1.0 and pulls really hard.
My idea is that 0.8 boost happens because the car runs some kind of safe map (maybe knock map??), and for the same reason handles the throttle slower and smaller? Does anyone really know, how exactly a signal of knock affect the m35's behavior?
P.S. Sorry for bad English, not my native.
