MHD Stage 1 93 Octane, review log

I have a 2008 535i Auto stock with Stage 1 MHD tune.

93 octane. All stock.

Can you guys take a look at the log? Should I hit more boost? I am seeing some corrections on cylinder #1, should I be worried?

When was the last time you changed the plugs?

Last week. Car has 50k miles on it. Going to do walnut blasting this week as well.

I think it might have a boost leak based on the boost plot. Also I checked and I have 5 newer style injectors and 1 original injector which happens to be #1 and it looks like I am having timing correction only on #1.

I also have a bad low pressure fuel sensor. It will be replaced when I do walnut blasting.

Installed new low pressure fuel sensor and did Walnut Blasting today. Valves were filthy.

Here is a another log from today. Looks much cleaner, no more cylinder 1 corrections.


Boost still feels a bit low after 5k rpm, drops off pretty fast. Should I see more boost with this map or this is just the way it is?

I ran this tune on my car and it felt considerably slower then the Dinan tune I had. Boost is right about where it is on your car - 11-12ish. Just not enough for me lol. I was told its not a big deal to run the stage 1 + FMIC tune.. even if you don't have the aftermarket FMIC. Go flash that tune - way stronger tune boost got up over 17psi for me.

if you do that, get some logs. I am going for a walnut blast tomorrow - everyone says its great. My car only has 34.5k on it but its an 08 and I figure its better to get them cleaned up especially since the car has been sitting for a while and is now being daily driven.

I loaded the V5.3 Stage 1 FMIC tune. It pulls hard, but i think the IAT's of 165 are a bit much.

Pulled timing in a couple of cylinders, at the beginning of pull and after the shift to 4th.
