I was looking at Race Chips website and was a bit confused over stock specs for the BMW F30 330ix which is listed at 248 HP. That is correct. The number listed for stock Torque is 350 TQ which is not correct. If you convert the actual torque to Nm instead of lb-ft you get 350 TQ. So the gains posted are first HP which says 303. Ok, I can believe that. The gains listed for TQ show 408 which is ridiculous if you assume they stayed with imperial measurements which would be crazy high. If you convert that 408 back to lb-ft you get 300 lb-ft. I can believe that and would actually be happy with that if it was true. The fact that they used imperial for HP and metric for Torque makes the torque gains look amazing. It bothers me that they mixed up the two measuring systems to make TQ gains look fantastic. Has anyone else noticed this? Has anyone actually installed a Race Chip? If you have what we’re your gains? I have written a letter asking them to explain the HP and TQ number gains. Will keep everyone updated.

that stock torque figure sounds more like the 330d

Whenever people mention "chips" for F series cars, I always respond by recommending a well known piggyback or flash tune if you're looking for a quick bump in power rather than something like racechip. In tuning, I think it's always better to go with the more well known brands, rather than companies that don't even list the gains in a legible way.

JB+ quick tuner and/or the Dinan sport tuner are the most common ways to add cheap power that are also made by reputable companies.

I totally agree with you and as soon as BootMod3 has a tune for my engine I will go with them. I was just browsing around for tunes and chips and saw them. Then when I looked at their specs I thought to myself, "No way."

DarkStarBimmer, those are the correct numbers for the 2017 330ix B46 engine. 248Hp and 258lb-ft of torque.

Thanks for the responses all.

I got the mppsk + DINAN stage I chip installed. On my 2018 440 gc and I absolutely love it.

The numbers quoted are unlikely to have anything to do with reality. I tried two of RaceChip's products (including their top of the range GTS model) and neither did anything to noticeably increase performance.

I also have an email from RaceChip stating that the quote numbers might vary by UP TO +/-5%. This is completely untrue - On my car, even if the RaceChip product had worked, the level of 'claimed' boost pressure increase on the RaceChip GTS (+0.2bar / +3PSI - I have this info from RC tech support) is insufficient to deliver the claimed HP increase (+52HP). The BMS Stage 1, which has been properly dyno tested, does deliver this level of performance increase, but with +4PSI boost, and high octane fuel.

In the end I went with a BMS JB4 - the marketing might not be as slick as the RaceChip, but it really delivers, and does what it promises to do.

Agreed. Stick with a piggyback until your BM3 tune comes out. I'm running the Dinantronics Sport tune right now, on Sport+ mode (+3 PSI) and 91 gas and I can tell you there's definitely a noticeable difference.

I'll be upping it to Race mode once I fill the tank with some 94 octane gas this evening.

I just ordered the Dinan JB+ and will get it on Wednesday. I will follow up with impressions a few days later.

Did you order Dinan sport or JB+?

Why are people still buying juiceboxes when the ECU has been cracked for a while now and tuned maps are available?

Price, ease of install, simplicity. Some people also aren't comfortable completely remapping their ECU and just want to throw a couple extra pounds of boost at the car for a bit more power.

A juicebox can never be a superior option to a tune unless the vehicle is still under warranty. Remember that a performance tune can also be reverted back to stock. A box is just fooling the ECU to produce a higher boost and fuel pressure. It can not only be very dangerous to increase the pressure in this way but in addition, will the vehicles other systems be compromised and might not function 100% which is not the case with a remap/flash. For example, is the DSC system using information from the ECU to know how much torque the engine is producing. With a box, will this information not be accurate which could potentially reduce the functionality of the DSC or even render it useless. Vehicles with an electric LSD will also not function as it should and might not work as intended. Fuel consumption readings will also be inaccurate etc. etc.

Check his engine.

For those with cracked ECU/Maps, it's like what was said above. Cheaper and people are more at ease when they see it's just something to plug in compared to this "complicated computer business"

Sure. I wasn't arguing that piggybacks are better than flash tunes, objectively they're not. I was just answering your question, providing some reasons people prefer piggybacks over flash tunes. Also, what BunkerJ said, the B series DME has not yet been cracked to be flashed, so piggybacks are the only option for those guys ATM.

EDIT: Thinking, I think it has been cracked but there aren't any tune's out yet. Still too early.

Your edit is correct. Cracked but tunes are still in the works. HCP has already tuned the F90 M5 (I think last week or just prior to that) but I haven't seen anything on the tunes for the B48/58 or other B engines.

Ok. I’ve had the JB+ for about a week now. Using my iphones GPS and an app, stock 0 - 60 was 5.4 best run. JB+ best run was 5.1 I also have an app that measures boost from the OBD port. I’ve no idea what stock was as I didn’t use it prior to JB+. With JB+ it reads 22psi at full boost. That seems a little high to me. I have the JB+ set at what they say is 4.5psi max. Anyone know what stock max boost is for the B46? I’m happy with the JB+ btw. Butt dyno says it pulls harder when it hits full boost.

[JR5674]

I too have a JB+. It’s been in for a few days. Quite pleased with results and power increase in my 2.0. With any modifications be aware of the potential mechanical and financial obligations that could arise.

Side note review ...took home a 2018 550m xdrive yesterday, dealer let me have for 3 days. It’s loaded w everything including “night vision” which could be useful if you live in heavy deer populations but I Hate the vehicle. It’s like it doesn’t know what it wants to be. M5 or regular 5series. Beautiful, Lots of power without the lovely M5 exhaust notes and touch. Feels like a boat. Even with 200+ less hp, I much prefer my 428msport to this 550m. I’m actually gonna return it today after just 24 hours. I actually prefer my suburban to the 550. Sure it’s a much different ride, but the Chevy soapbox with an interior like a living room and wide soft recliners makes for a super comfortable ride. The soapbox, in my opinion, is the most comfortable ride on the road. The 550 is ok/good at many things but great at nothing. Viva the 3/4 series!

Not sure enough experimentation has been conducted to be able to tell, but I'd take a gander to say it's a minimum the same as the N20. I would say it's capable of higher though.
