I have an S5 TII and I just replaced my turbo with one that has a ported wastegate (I blew my last one cause it didn't and I have a 3" full RB exhaust) and now when I try to boost I get a backfirey jerky type thing happening... I took the stock boost control thing off (so it should only be at 5.5 psi) and on short test drives I'll try to boost and it does that (but I can boost a little before it starts), and when I get home the turbo will be red hot, sometimes starts to smoke, one time started leaking coolant. I checked the engine codes and it gave me an 01 which is the trailing coil, but I replaced that and the same thing happens.

any ideas?

well check the plugs make sure that that isnt the prob. then check your a/f and you may be hitting fuel cut

I checked my plugs today, they looked fine. I have new wires in the mail, even though my current ones aren't too old. and I have a fuel cut defender on there so it isn't feul cut, even though that's what it sounds like.... (I don't have a a/f gauge)

Check your wastegate line and just for the fun of it try unhooking your fcd and see what it does.

your timing could also possibly be off, since your turbo glows red after, etc.

man mike i woke up this morning an i almost called you. i was gonna ask if you had an fcd cause thats what i feels like. call e tonight an well play with the timing and try unplugging the fcd. ill bring over a spare trailing coil and we can try that as well.

check your timing. Your tach working?

his tach works fine. i remember him saying it stopped working once before he replaced the trailing coil.
