Several picture when I doing the test...


When I drive my baby home, driving experience is really GREAT and feel like a totally different car. Good job Racechip here...

During this long waiting period, I am wondering is there any chiptuning mod will further improving my new baby's performance so I went here to find any input or not then I found this thread. Anyway, hope the picture here will help to explain a little for this discussion.

Basically testing environment is as below
1. test machine is Dynojet.
2. Car configuration a. Stock
b. BMS F10 N55 intake
c. BMS F10 N55 intake + Racechip Ultimate map E1
d. BMS F10 N55 intake + Racechip Ultimate map F1
3. Each config will test 2 runs.
4. Each config will choose 1 result to show
4. For some reason that Dynojet can't display rpm correctly so it can't show torque figure correctly but power figure should be correct.

Then the attached figure is for you to comment.

Anyway, I am not selling anything here just show the fact that I just got today.

Cheers

How did you get less horsepower with the BMS intake? Good findings otherwise!

[yoyoluking]

I am also surprise about this figure. They claim BMS intake can increase 10HP there but looks like a total different story...

Looks like you guys are just reading his dyno chart wrong. The stock run and stock +intake run are basically identical at 285whp. Which is to be expected. The 295whp figure is a shift spike.

The run with the tunning+intake added is ~30whp higher. Sounds like the tuning is around +3psi, similar to the BMS Stage1.

Thanks for your explaination and you are right. Run 2 should be a power surge at the end of the test. The actual run2 power number is around 283whp as well.

Looks like Intake won't help on increasing power but the sound improved a lot that's for sure...

One more thing worth to mention, Racechip claim that each adjust on power switch will increase 1.5% more power and looks like valid in this case as below:

Run6 max power: 310.2
Run7 max power: 314.5 increase 4.2 whp around 1.35% increasing rate.

This give me more room to imagine that I still have 8 more adjustment level... So it will be very funny in future mod...

you say you're not trying to sell anything but your license plate says "RACECHIP". are you sure you don't work for them?

Of course not, I ask racechip guy to hide my real car plate so they use theirs. Come on, is that so serious? When we talked about JB4 then everybody knew that's from BMS...

A lot of challenge about the real figure then I provided it then it turned that I am working for Racechip? What kind of logic behind this. Are you working for BMS???

Yoyo

i was just checking.

there's been so much speculation so i was just being cautious.

[RambleJ]

So the performance is on par with the JB4, so then why would someone pay double the price for it?

[yoyoluking]

I am not in the state so not sure the price there. But here in Taiwan the price for both product were almost the same...

What dyno is this ?

I have a RaceChip for sale. PM me for a great deal with your phone #.

[eplace]

Damn, I love that digital gauge!

[BlackBear]

I have a RaceChip for sale.

Also have a set of rims for sale.

[ZRsaad]

so is RaceChip any good compared to BMS or Dinan?

[BananaCar]

Looks like there isn't much value until you reach a very high speed. Price depends on how much your local dealer charges. I'll stick with Burger as OP stating he is not affiliated is very suspect.

thanks to Klecha_man and dr.mba and yoyoluking!

Getting a RaceChip Ultimate for $594 from 1 of the authorized seller in the US =)
The difference with RC Ultimate is that, its pretty much a JB4 Stage2 but more stable and doesn't tap into power/ground or canbus. It's easier to install/remove and produces the power from start also without requiring any other mods on the car.

I will believe when i see some numbers.

I would like to see a side-by-side comparison of RaceChip, BMS (Stage 1 and Stage 2) and aFe Scorcher.

I run a stock setup up with 93 octane and would like a decent bump in the front end torgue with a couple extra ponies. I live most of my life between 2000-4500 RPM.

Wish I had saved some more $$$ and ponied up for the 550i. Before this forum (and others), I thought with a twin turbo it would be relatively easy to get 350WHP and 400ft/lbs of torque out of the 3.0L N55. That really would have been enough for me. I couldn't have been more wrong. Seems like BMW has them either fairly optimized or locked down on the newer F10 535i.

If I am missing something here please let me know. Catless downpipes are not an option for me, intakes seems to make little difference other than better sound and cat back systems are expensive with relatively little gain in power (although the do sound and look better but at a cost of $1500+ USD).

Frustrated we can't get much more HP out of these without spending as much as buying up to a 550i.

Anybody have any other experiences, please let me know.

F10 535i N55 is not Twin Turbo. It is a Single Turbo with Twin Scroll.
