I have a 96 TT Auto and have just fitted my second decatt (HKS 3"), i also have a TRD exhaust system just recently fitted, hks bov (not that this will make any difference iam just reliving my youth;)).
Iam peaking out now at 13 psi on occasions (with the first cat still in) which i suppose equates to 0.9 bar..iam pretty happy so far and thinking that for the preservations of reliability i might end it there!
Oh I do have a HKS panel filter on the way..iam just in a dilemma whether or not to go fully bpu.
And what's the con's on leaving out the sensor on the first cat if i did decide to go that way?
Thanks:)
Oh yes boost readings are through my AEM guage
