Read thru 100s of pages of people talking about what the Racechip does to the seat of their pants, many promising getting their car dyno'd with threads reaching 10 pages, but NO REAL RESULTS OR DYNO's....

Did I miss the thread where someone Did a before and after dyno?

I tried the JB4 Stage 3, but they couldnt figure out how to tell me what wires to tap and after an hour on the phone they them selfs didnt know, so I returned it. But Racechip looks like it produces great #'s but the same people on all the boards are the only ones backing RC, but wont post up Dyno results...

Anyone have any proof of what RC does for our F10's? 535 or even a 550 stock???

Preaching to the choir man. Haven't seen one independent dyno for the 550i or even the 535i... I really think that this only pumps out as much power as the BMS Stage 1.

All we heard about is how it feels....

[AddyDaddy]

Its amazing across all the boards and texts there isnt a single Dyno test..... Its crazy.. If I got one , you know I would have a baseline and then the results PERIOD..... it would be done with in a week lol... lets sign a petition lol.....

Maybe RC only improves your mpg from 20 mpg to 21.5 mpg's

Or possibly over priced sprint booster

thanks,
I saw that, but, is it me or did RC do nothing at all? It looked like the BMS shaved a 10/th off, but, thats a heavy X5 compared to our 5 series and a different engine. I see there is somoene going to the dyno today with their 5.

TShoot has had BMS Stage1, aFe scorcher and RaceChip on his 535
He can comment and has thread

Unfortunately doesn't look like any N55 or N63/N63Tu has Dyno'ed w/ RC but I have dyno'ed on the N20 side and raced against N55 stock (won), raced against Dinan Stage1 (1/4 mile drag strip 5 runs back to back) on stock setting.

Why not buy RC drive it for 100 miles on stock setting then increase to another setting, take it to the Dyno from the highest setting then down stock setting, then baseline

And to add what many have added coming from BMS product, the Racechip just delivers a way more smoother power and more consistent on top of that having a better build quality box.

Currently there seems to be an issue with the RaceChip Ultimate for the N63tu motor.
I am still in the talk with RaceChip to find the solution, so I couldn't report anything back but the BMS Stage 1 for N63tu motor gives -/+ 30 whp and -/+ 5 lbs/ft torque gain.

seems like sprint booster + bms stage 1 combined in one box from what ive read so far about the Ultimate. I'm very curious about the GTS Black
