I currently have an AFE scorcher module on my M235i xdrive and though it adds a bit more power, like many people on this forum, I always want more! My understanding is the AFE module adds 3 pounds of boost across the rpm range. I am considering getting the Dinantronics sport module though to replace the AFE one, since it sounds like it adds slightly more boost, up to 5 pounds I believe, and allows you the ability through an app on your phone to adjust and monitor boost, which is really cool. My question is will the extra 2 pounds of boost make much of a difference in terms of seat of the pants power? I know it won't be like a night and day difference, but I'm just looking for a bit more. Also, I know the JB4 would add a lot more power, but I'm not really interested in it due to the complexity of the install and the fact it may be too aggressive for what I want.

Any thoughts/insights are appreciated.

Interestingly since it's already connected to the maf. I'd think it would be ideal to contact Dinan, or hopefully they read this and give insight directly

I wouldn't run both, personally. If you intend on getting more power consider just going to a full JB4 instead. Do it the right way where you are controlling fuel ignition and boost and have dedicated maps for your mods and octane. Blindly adding post and scaling it across the board is not ideal tuning.

Thanks for the thoughts. Sorry if my first post wasn't clear, but I wasn't thinking of stacking them but would remove the AFE module and add the Dinan one. Just trying to decide if the Dinan one will give me enough of an increase over the AFE to make it worth $299.

I would but I have the m performance exhaust now and really like the way it sounds so don't want to mess with that.

I have the Dinan Sport on my x3 (n20) and noticed the difference. I can't say if it 2ould be noticeable on the 235 though, but I felt it on the x3 and breathed some life into an otherwise "tired" n20.

I'm sure you'd likely feel it on the 235 as well. Am I running a stage 3 Dinan on my 235 as well.

[Benandluna]

Oh ok haha, I was confused by stacking too.

Hmm I personally think that since it sounds like the jb4 is a little more aggressive than what tune you are thinking about. A Dinan may be a good idea, perhaps combined with there intake and as someone mentioned a sport cat. It shouldn't mess too much with your sound, but the power is awesome.

If you want in between a jb4 and what u have and want to ensure warranty isn't an issue. Perhaps a stage 2 Dinan. It's more pricey but a piggy and a good sport cat is already over a g.

You cant add 5psi on a stock car, it is not safe.

Max you can add is 4psi
I would do BMS JB+ instead ... Both will get you same power and BMS is cheaper

Thanks for the suggestion, but according to the Dinan website, stage 2, which includes a Dinan intake and exhaust, costs $2300. That's a lot more than I want to spend right now and considerably more than the Dinan Sporttronics module at $299.

I'm not sure why it wouldn't be safe to add 5 psi of boost to a stock car, especially considering I read somewhere on this forum that this is what Dinan module does in its most aggressive setting. By the way, not sure if it matters but I currently have the m performance exhaust and AFE intake on my car.

Stage 2 dinan does not require the intake and exhaust. It is recommended.

I forget the modes on the JB4, if you can get a JB4 and just dial it down that is another option.

Perhaps the middle ground would be a dinan sporttronic topped off with a nice sport CAT.

I think the Sport+ setting on the Dinan Sport adds +4psi.

That does NOT include the intake that's an extra $617. That's mandatory, exhaust is ever more but that's purely optional.

That said given that you've already had a competitor product on your car I don't know that you'd want to spend the extra money for the "real" Dinan stuff versus sport. Someone may know better than me but if the history of you messing already already lives in your car somewhere I can imagine warranty (one major benefit to spending $2k+ on Dinan) could be a huge headache. BMW says it's not their fault, Dinan could blame it on whatever you had installed previously, etc etc etc.

I am skeptical that a difference would be noticed perhaps you might notice a difference in power delivery that might make it worth it to you. You could always sell your AFE to cover some of the costs.

Better yet, take it to a dyno shop and get a pull done with the AFE, then put on the dinatronics for next pull and you will have your answer. Might run you $80 to get that answer. Then put loser up for sale in classifieds

well if that's the case that it only adds 4 psi, then it wouldn't be worth it. do you know where you saw this number because I thought I saw 5 psi somewhere?

that's a good idea about the dyno as I hadn't thought of that. I was hoping someone else on this forum had experience with the 2 modules and thus could speak to the difference, if there was any.

I have the Dinantronics module on my 235 and love it. "Race" mode on the app adds 4psi boost and it is absolutely noticeable. Bought from a forum sponsor and got a great deal.

Race mode gives you +4psi.

Thanks for the link, that's helpful and confirms the 4 psi number. It might not be worth it to switch for 1 extra psi; however, the fact you can adjust the boost via the app and can monitor it is pretty cool. Also, the fact Dinan has more of a relationship with BMW than any other tuner makes me think that the techs who work on my car at the dealership would be more likely to turn a blind eye to the tune.

When I ran across the Dinantronics Sport add-on for only $299.00 the other day I thought, hey, that's pretty cheap for adding ~42 HP and ~45 ft. lbs. of torque.

Then I saw Dinan's graph and was pleasantly surprised that they measure the stock N55 at 340 HP and 336 ft. lbs. of torque; up from BMW's claim of 320 HP and 330 ft. lbs. of torque. A tidy little increase, I thought.

So in reality, it seems that the Dinantronics Sport really adds about 22 HP and 39 ft. lbs. of torque. That's still a good gain, but after reading that I already have 340 HP and 336 ft. lbs. stock, I'm happy.

that is good to hear. sounds like it is well worth the $299 price.
