FMIC needed with JB4 and downpipe?

Hi everyone, am selling my 528 and and buying a 2016 435Xi. I am looking to mod the 435Xi and have kind of settled on the following performance mods:

1. Charge pipe
2. JB4 tune with E85 (4-5 gallons)
3. Catted down-pipe like a FabSpeed

My question is, will an inter-cooler (FMIC) be a worthwhile upgrade or is it a "nice to have", but really not necessary for the upgrades listed above?

Thanks, and excited to join the F32 ranks.

Hi,
It depends if you are going to track the car. If so you can end up with heat soak with the stock intercooler which will reduce power. In that case an upgraded intercooler will allow you to run the car hard for more time with out the heat soak. If you are not going to track the car than I dont think you need to upgrade the intercooler. You dont say which charge pipe you are going to install. I would recommend the ER charge pipe. I have it in my car and the quality is excellent. I would encourage you to install an exhaust that breathes better with the upgrades you have planned. Mike at n54 tuning is an excellent source for the items you want and he is very knowledgeable.

Thank you very much for the advice. So you recommend upgrading the exhaust along with the down-pipe, didn't realize that was necessary. I will look into exhausts; I like a quieter or non-raspy exhaust, more low and controlled.

This car is a daily driver and do not intend to autocross or road race it. I was getting very wishy-washy responses on the FMIC for the upgrade level I was pursuing so was hoping for more definitive responses from people who have done it.

I'll look into the ER charge pipe.

I suggest you consider the Bootmod3 instead of the JB4. Alone, a new intercooler will improve performance.

I have read that a intercooler will not necessarily increase performance on our cars. I cant speak from personal experience as I have not changed out my intercooler. I have upgraded to mppk with mpe. I also have an ER charge pipe and a sprint booster. Even though the mppk is a mild tune from BMW my car pulls significantly harder than stock before I did the mods. More important to me is the every day driveabilty of my car is excellent and I enjoy driving the car quite a bit more.

What is, and who does the Bootmod3 tune? Is this a piggyback system or a flash?

OMG, I am so dumb, BootMod 3 is BM3.

Ok what are the pro and cons between BM3 and JB4? I have been emailing with someone at Burger Tuning and they recommended the JB4. Don't they also write the BM3? I read that the BM3 does not require a flash anymore and can be done with a handheld.....

BM3 is a flash, and offers many choices of desired flash. The simplest way to transfer the flash to your car is with a laptop computer. You can use a handheld device but is costs @$300. You may already have a laptop - or can borrow one.

OK. I think it's time I speak with a vendor that can help guide me. A lot of variables hear.

I was able to do research over the weekend and I think I will be getting a Bootmod3 tune. A lot of good feedback on this system, and I like that users say that it drives like an OEM tune.

OK, thought I'd let everyone know what path I decided to go down, and then let everyone chime in if they'd like. I bought the BM3 tune, charge pipes and a CSF inter-cooler. I decided to break this into phases since I am picking the car up today:

Phase 1 - drive the car around for a week or two just to get to know it

Phase 2 - download the BM3 software, use the Stage 1 93 octane tune, and install the charge pipes and inter-cooler. Enjoy that for awhile, maybe until next spring in Michigan when the snow melts and weather gets nice again (April/May)

Phase 3 - add a catted down pipe and a Stage 2 93 octane BM3 OTS MAP with an E30 blend

I chose the Bootmod3 tune because of the feedback regarding how it is quite smooth in its delivery, like an OEM tune, but with a lot more power. Also, the customization and data-logging ability is attractive. I chose the CSF FMIC because Mike at Extreme Power recommended it, and it is a 6"+ inter-cooler with a stepped design.

That's the plan for now!

I current run a stage 2 tune on my 335 with a fbo and would highly recommend the intercooler not so much for HP gains but if you donít you will notice lose of power after a pull or 2 Iím also running bm3 found a 3rd Bluetooth obd agent on eBay for 100 works just fine I change my tune on the fly depending on what gas set up Iím using also using the tcu time makes a big difference in 6th gear

I appreciate the insight salxrod, I will install the FMIC with the Stage 1, tune already bought the CSF intercooler and ER charge pipes.

On another note, have been driving the 435iX around, and I absolutely love it, actually like it more than I thought I would. A great balance of sport and finesse.
