Congratulations, you've turned it into a DSM! :)

More like welcome to the world of direct injection bull sheet!

How fresh are the plugs and coils? I wonder if you might be experiencing the carbon build up issue on the intake valves.

I cleaned my intake valves the other night and the car runs way smoother now.

Plugs are fresh, coils are stock I believe. After the reset that night it has run just fine. I did some logging last night and it was holding good timing. It was not holding boost well though. I have the meth bung on my charge pipe and I am going to make an adapter to do a boost leak tester. I want to make sure I don't have any leaks. I don't really think it liked being on the dyno.

Hughes- running 10.2:1 compression and boost makes things a little trickier than normal, not to mention DI. It looks like everything is just fine now, I logged about 5 runs last night. I need to see what levels of E85 we have too, I don't have a tester.

Boost leak, makes sense, I wonder if that explains your lower then expected dyno pulls too? Also wanted to mention my MPG went up again, after the intake valve media blasting, I gained another 2 mpg for 27 mpg highway and no more cold start misfires.

Well I didn't even have to do a boost leak test. I had been thinking about it recently and wondered what was sealing up the metal coupler side of the charge pipe. I did some more checking and I pulled a noob mistake. The new pipe didn't come with an o-ring and the other one came off with the old pipe and didn't stay on the TB. I pulled it apart tonight and got the o-ring in there.

So, I have been running with a huge boost leak! That explains why the dyno fell off so bad and I was not holding boost as good up top as I thought. Now I want to get back on the dyno! I can't wait to drive it tomorrow and see the difference.

Yikes, turbo was workin hard! Glad it was an easy fix.

[simulatedwood]

Excellent news! I bet it feels a whole lot better now.

Yeah, it pulls much harder now and doesn't fall off up top as bad. I tagged Chris Carey on FB to see if I could get in for a couple of pulls to see how it looks now. I am very impressed with the car for only having a tune on it. It is definitely a 12 sec car now, which isn't bad for it weighing almost 4k lbs.

Good to know about the o-ring thingy. I will definitely watch out for that if I ever come to it. Keep us updated.
