Very nice. Nice on the DCT car too, wish my car had one of those.

Jet, thanks for sharing. Did the other guys run on JB Map 5 also? And is his also running e85? Did it throw any CEL on dynojet?

**JET** · 05-03-2014

His was E85 also. AWD is costing me about 20whp the auto another 15. No CEL's. I did get a goofy reset after I drove it. Not sure the AWD setup liked the dyno since the rollers aren't linked. Here is video of it, nothing exciting.

Agree!

Yep, the car isn't happy about something. Racing a modded G35S tonight and it threw me in to the stock map after flashing the CEL. I also noticed on the first race with him that it was lowering the boost in the middle of the rev range(beat him by 2 car lengths to 80). I am going to toss the laptop in and do a little logging tomorrow after work.

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.

JET - keep us updated. And I finalized the deal and have the car in my garage now :-) Before reading into the JB4 stuff, i first need to finish all the menus though - just spent a good 20 mins to set up the homelinks - had to run back and forth like a monky :-)

Quick question - as for 93 pump gas, i believe the majority on here and EvoMN would vote for BP, but besides BP, are other ones you can recommend on? How about Costco premium gas? It claims it provides 5 times more protection and cleaner, and in fact, I do like all Kirland products - especially the Toilet paper ;-)

Congratulations, you've turned it into a DSM!

ouch.

dang!

**JET** · 05-08-2014

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.

A//// Guy · 05-09-2014

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

simulatedwood · 05-09-2014

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

**JET** · 05-09-2014

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.

EnjoyDriving · 05-09-2014

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

Hey, i've just come across this BMW recall on 2010-2012 http://www.autoblog.com/2014/04/11/b...ars-worldwide/
Did you guys get any alert or mail regarding to this recall? I believe Jet's and Rosey's are on the list.
