i couldnt agree more.
because ATP makes them. and they don't make a different compresor housing that would bolt up to the speed6. only option for that is to weld the wastegate shut and run an external one.

It's a Garrett CHRA and compressor housing, but ATP designed and manufactures the exhaust housing--which is a POS and causes boost creep..
Well let's be clear ... it causes boost creep when the throttle is programmed to be fully open by an ecu flash. No one had problems with boost creep until they started getting these throttle flashes.
not to start an arguement but buying a turbo upgrade is to make your car faster now why wouldn't you allow the throttle open the entire rpm range? if you wouldn't get the flash then why go big turbo? the fact remains not to point fingers or whatever but this problem should not exist point blank. i know we can ALL agree on this.
I hear ya Dr D but put yourself in the shoes of ATP. You invest in putting out a turbo that work fine on the DISI motor with the way Mazda has had the ECU flashed (ie. throttle closes after 5500 rpm). You sell a bunch of them and life's ok.
Then CP-E, Piasini, and Cobb find a way to alter the throttle mapping and they program it to stay open all the way to redline and all of a sudden those people with the turbos that get the flash are having problems with them.
Is that ATP's fault? How did they know someone was gonna come out with a flash that was gonna 'cause the creep? Heck, they wouldn't have even been able to test it on a full-throttle car as no one had yet done it even if the thought crossed their mind on what would happen if the throttle stayed open all the way. Again, put yourself in their shoes as a businessman.
Now can they use this opportunity to re-design the wastegate and make it work? Absolutely.

Hate to break up the lovefest, but my ATP turbo induced creep well before a flash was introduced. If i'm going to design a baseline 1700 dollar turbo with a gt30,35,42 compressor housing, that turbo for one is not going to be tested on a vehicle, but on a rig that supplies the exhaust housing an accelerated pressure that is held constant, while i'm measuring boost on the other end. Immediately I would have had conclusive evidence and reason to increase port diameter or adjust actuator geometry. This is just the basics to how turbos work and to deliver a quality product. They fell short and really don't care about it or else they would chime in on forums and talk to their customers who have expressed much concern. When it comes to this particular issue, it is either two things, lack of knowledge or lack of care. You pick which one.

That is exactly why I spent my 2k on a custom manifold and DP so I could run a standard T3 gt35, with Garrett housings and an external wastegate..
I frequent all the forums and that's the first I heard of that ... I'm not too big to say "I stand corrected".
