So in others words there would be no traces of you flashing back and forth from stock to tuned? Yeah I know with my Cobb is supposedly left no traces and I would do the same on my 335xi when bringing in for service or warranty as that was also a cpo car. Thanks for the info

The dongle is optional. The man is using the product and he just said $895. Only thing needed is the good old ENET for about 19 bucks on Amazon!

Gobs of torque and power feels effortless (if that makes sense). The throttle doesn't seem as responsive with the tune compared to the stock tune. I've also noticed that the transmission doesn't like to downshift at the tap of the throttle as with the stock tune. In other words you really have to put your foot into it in order for a quick downshift. For example, if I'm cruising around 45 mph and low rpm... if i step on the gas (1/4 to 1/2 throttle) the rpm's will climb from (let's say) 1200 rpm instead of the transmission downshifting to a lower gear. Unless i put my foot 3/4 or fully to the floor it likes to remain in the gear it's in. The car seemed much quicker to downshift with the stock tune. This happens in both comfort and sport mode. The power is always there so this isn't necessarily a bad thing, I'm just not used to it. I've a message into HC Performance in Denmark. Next step is to do some data logging and get a custom tune from them.

Yeah for sure with the custom. How much on top of the bm3 costs would the custom tune be? Wonder what's up with the throttle and downshifting? I'll probably still go this route in a week or so. Debating on the bpc tune as well.

I'm in the same boat. Debating between the same two tunes.

Vivid racing also has a tune for those interested.
Those throttle issues are worrisome.
One of the reasons I was hesitant, not just in flash tunes, but wired ones too.
Some folks reported issues.

I'm not sure but I'll get all the details when they get back with me.

As far as power from a dig... i did a roll out the other day (let off the brake and punched it in sport mode) and it threw me back and pinned me to the seat. Really wasn't expecting it to launch me like it did. Another trip I power braked it to about 1500, nailed it and it hit the rev limiter. Do you know if there's anyone else on this forum already running this tune? Would like to compare thoughts

Not that particular tune, hence the interest in it as an option. DusH is the only one to my knowledge that has the BPC flash and he really likes it. Don't know that he has ever acknowledged throttle and gear issues.

I'm more comfortable with a quality flash tune, but I agree the shifting issues are worrisome. What really worries me is the longevity of the motor. BPC claims a 127hp gain to the wheels which easily translates to 140+ at the crank. That's an amazing power boost for the money, but can the bottom end really handle that much added power for long? I'd wondering if I'm better off with a detuned flash that provided 75rwh in the hopes of better engine life.

Bottom end on these cars can probably handle 600awhp reliably. 800awhp is probably where you have to start worrying.

I would actually think that 127 awhp is closer to 160+Hp at the crank, which is crazy for just a flash, think about lots of drivetrain loss awd and auto trans . Didn’t your car stock on mustang dyno put down like 350 and crank it is 445. Also like mention by pits200 , I believe it’s BPC that has a 550 running like 600 awhp on the n63 and think about it not like your running all out all the time , it should be fine with that bump in power as long as your not beating on it non stop.

I had a 112k miles 700awhp n54 on a completely stock engine. These boosted cars from bmw are easily tunable for power and minimal engine work. Always use enough octane and don't try going crazy on ignition advance and boost when making custom maps. Adding 100awhp on a v8 twin turbo is cake. Remember the nice thing about a flash is you can get horsepower by other methods other than upping boost

Hey pits200 I remember reading about your car on the n54 forums I actually had a 335xi myself, weren’t you running so sort of 60 series turbo , 6266 or 6466 or something along those ? Car must of been a blast to drive pun intended

Ya, I think I remember about your car too. I was running twins but was always too worried about the transfer case or differentials exploding along with 5h3 transmission. With a new addition to the family, decided it was time to move to another suv in the family.

Car definitely was a blast to drive.

Thanks for the feedback pits200 CT335xi. I must say I'm really surprised that no one is worried about adding 140+ hp to a stock N63TU.

Yes, that is true about my dyno numbers. I was being conservative when I said 140+ at the crank. I definitely wouldn't be beating on it non stop, but I have seen 15psi of boost during moderately heavy accelleration (not to the floor) on the highway. I'm thinking that if a flash allowed, say, 20psi, you wouldn't have to be beating on it to see those boost levels and the added engine stress that comes with it. I guess I'm just being overly conservative with this notoriously troublesome engine.

Don't get it wrong, there is concern when adding that much horsepower but it's not with the engine being able to handle it but how is it being achieved. Are they changing vanos, updating fuel tables, maxing out ignition advance. As said earlier, horsepower comes in many fashions, if those 130awhp have all the proper ecu updates then the engine should easily handle it. Also, there are probably a ton of 550s out there pushing big power, the f15 is a bad example to use when looking for people pushing 600awhp.

I guess that's fair. Thx.

Question: are you able to log in and check what maps they have for 2017 X5 35i?
I emailed them and the guy couldn't give me a straight answer. It sucks that you can't see the maps before you buy. I dont feel like buying anything blindly.
If you get a chance, please check on the maps.
Thank you very much

I think mhd supports the 35, go that route. Proven with tons of maps and much much cheaper.
