there are a couple of places modifying the ko4. from what I've heard, mazda screwed up in the relative sizes of the wheels. the worked ones are supposed to be much better.
 
Still running into some problems with stock bpv...gonna try some more things today. Perhaps the corksport DP is throwing it off.

Another guy is having the exact same problem as me, and Christian thinks its overboost (not fueling problem).

You think the Corksport DP is THAT much more less restrictive than Cobbs? (how would we know..its not out yet! lol). I mean it's just a fundamental design difference...with corksport's divorced style, etc.

BTW I am running a high flow cat in the mid pipe so its not due to that I dont think.
 
it's definitely a weird thing. or maybe not. do you know of anyone else running stage 2 maps with no problems?
 
exactly why i am waiting a month or 2 before i am gonna get it.. let the bugs and more maps come out.
 
Wastegate/boost control issues due to divorced style downpipe perhaps? I hope it's not a limitation, just something that needs to be tweaked in the tuning or something.

I'm sure when cobb releases the tuning software, it won't be as big a problem. is the car learning the maps better now that you've driven it some?
 
I've been switching around. It seems to driver smoother over more time/power cycle, but gets the stutter every time. ok gonna go test some more
 
its not that bad i did it in 2.5 hours with jack stands but i get payed to turn wrenches all day i could probably do it in 1.5 - 2 hrs now
 
what is up with all the people saying it took 6 hours? did you go from the top or the bottom? also, do you get any smoke? I'm guessing you have some sort of catless midpipe also?
