i have owned my viggen for a month now and i am starting to think about tuning.
i have noticed that it has got 2 cats on, surley this is massively restictive.
what exhausts are on offer??
at what cost??
would the viggen benefit from just a front pipe with no cat on??
can a after market air filter be fitted??
would this bennefit the viggen??
can the boost be increased??
by how much??
does it need other things when the boost is increased??
can it be adjusted manually or does it have to be donr through the ecu??
i have read that the viggen can make full power at high altitude by increasing the boost it'self through the ecu upto 20psi.
what psi does it run normally??
can the car be fooled to think it needs to increase the boost??
sorry about all the questions but i have done a few searches on here and still not sure, so i thought it wise to ask people in the know :cheesy:
