Back on topic.

Any updates on your experience with the car? I'm hoping you were able to drive it around a bit?

Yes in fact I did this afternoon. I'm having an issue with stg4 which is why I haven't given my opinion on everything yet.

Gotcha, thanks. I hope you get things sorted quickly and easily!

Do you mind sharing what type of issue?

Anyone else considering going with either the upgraded fuel pump or fuel pump upgrade kit? It's been mentioned that fuel flow may be an issue with increased boost under heavy load. For this reason, I keep my fuel level at no less than 1/2 tank. The kit is considerably less expensive than the entire pump but the website has the same description for both units. Need insight here.

If you keep your tank at over half a tank at all times there is really no need for the pump. Fuel starvation on the M2/M235i happens with less then a 1/4 tank and when the car is pushed hard for an extended run. The stock pump just cant keep up with the demand in that situation and the smaller saddle tank drains faster then the pump can replenish it.

As far as the difference in pumps. The kit is great to utilize if its a new pump being used. However the thing is made of plastic so over time it becomes brittle and doing modifications to the pump in those conditions can damage it to the point it is unusable. Then you will be waiting for a new pump regardless. Hence why we offer both options.

Appreciate your non-sales tactic honesty

I'm getting the upgrade done while they're doing my Stage 4 upgrade. I have 10k miles on my car, so I'm assuming I shouldn't have to worry about deterioration for awhile. I like the added insurance.

[switlikbob]

I'll be getting the pump as well.

Without 93 octane are any of these upgrades significant or are you taking out a good 30-40% of the gains on each dinan scenario?

With stage 1 tuning and 91 octane you will have very little benefit as the gains even with 93 are modest. With the big turbo/stage 4 setup and 91 octane you are looking at about 20-25% less gains as a rough number.

In general 91 octane will yield about 20% less of stated gains on the stage 4 setup....post #18 of this thread

Dinan, I recently upgraded to stage 4 at the same time have jb4 set on 4 which is to my knowledge only for logging purposes only. Will this still affect the dinantronics at all?
Anyone feel free to chime in

[DrKevM5]

So you're running both Dinantronics and JB4?

I kept jb4 on only to continue having the cel of since I have a catless DP and wanted to log as well. I have never set it to any maps since they are both piggy's which can cause issues.

Anyone have updates or personal reviews of the kit?

Yeah just did mine a few days ago. Will post dyno run this weekend

[serrated]

Still happy with mine. I just wish it were cheaper.

Didn't your post mention some issues with the tune?

My issue was with power delivery. It was a concern to me because it didn't feel much different than before in regards to power. In fact, what lead me to believe something was wrong was when I switched it to bypass mode. In bypass mode the car felt and pulled stronger. Don't have any data as of yet but will dyno the car Sat.

Was it a dramatic power difference?
