Invidia already has one out, catted and catless.

Ahaha, nice catch. That sort of slipped my memory when I tried recalling who had the perfect S2 tune.

Isn't the boost creep only in the Cobb S1 map? The Perrin S1 map that I'm running has no issue with this.

I don't have any issues with the Cobb stage 1 map either and I was doing some 4th gear pulls when it was 5C outside. I'm just waiting for it to happen...though my car seems to have taken well to the tune.

If that is the downpipe I'm thinking of, that is not a true divorced wastegate downpipe. The Invidia pipe is simply a bellmouth with a divider. I haven't seen any true divorced wastegate downpipes yet.

I'm not sure where it was exactly, but I was reading it in a post earlier today... The boost issues have been occuring for people in 5/6th gear on the highway at low RPMs when they decide to mash the peddle instead of downshifting.

I honestly think from hearing people's responses so far, that if you avoid the reported issue circumstances, then the Cobb S1 map pulls harder than the Perrin S1 map and has no other known issues.
