Hello Everyone. I have done a search on this and came up with nothing that answered my question, so I am going to try now. I have a 94 tt six speed. For mods, its got a downpipe, HKS superdrager, bleeder T,BCC and the 12v pump mod. My problem is this...Now that it has gotten colder, I have been hitting boost cut alot more often even with the BCC installed. I tuned it to the specs on MKIV.com when I installed it also. It cuts out at about 18psi which on my car is between 4500-5500 rpm when I am really getting on it. I am running the stock plugs on stock gap as well. I have also played with the adjuster on the BCC in both directions trying to get something better out of it with no luck. I have pulled the EFI fuses to reset the maps as well with no luck. Any info would be greatly appreciated as I would love to fix this.
