Check your timing - aside from that I shortened the Bell downpipe - I know it was like multilating a sculpture cause it is georgous (SS) but after I shortened it (with a cutoff wheel mind you so it's not really mutilated all that much) my overboosting went away completely... Food for thought. Stock on S3 is 6 - 12, start low and tune and slowly turn it up (obviously). But check your timing with a timing light just as a sanity check. If it's off you can overboost also inadvertantly.


Any which way Bell will get you sorted out or try their best to - thx Steph :-)

Damn S3 is responsible for 4 sets of tires now :-P I love this ****. Give Corkey my regards.

How exactly does shortening the downpipe make you not overboost?

 

No idea but it did.....

 

I meant fishy in that he has a less restrictive exhaust side and yet his boost is more controlled than mine. The timing is accurate also.
