Think of it this way - changes are always being made, tweaks to settings, fixes for weak bolts, bad fittings, etc. I can tell you from a resale perspective i got 18k for that 335 and would have got a shitload more if it was Dinan tuned due to its legacy.Īt the end of the day, you want BMW to be able to detect this stuff when something horrible happens.

The money you save will ultimately be paid in some way.Įnd of the day, do what you want.

So the choice is non aggressive and reliable and can get serviced, or full retard and pray it doesn't blow up. It was fast as hell, blew away lambos and everything else but it was unreliable. I had a 335xi over 500whp with intercooler, DP, MPE, COBB, turbos, Jb+, Meth, OCC, e85 mix or Race Fuel, and everything else you could buy for the car and it blew up 7 times in a year and threw codes and new plugs every 2 weeks. Most of this is self installable, but If you want BMW to do it, expect another 1000.00 in service costs.

Its expensive and not as aggressive as other options but, you don't have to worry about anything.Ģ800 or so on piggyback and stage 1-2 and 3 software updates.

If you want to tune and get warranty, your best bet is Dinan. I'd also always bring the car in with the second key fob, the one no one uses and wouldn't show anything on. Now if you cleared all your codes prior to brining it in for service with Bavarian Tool or similar, there would be no codes available to check. So what you're saying is that AA8 or JB4 for example are absolutely not detectable if removed and Dealers can not bring back Data showing abnormal boost levels ? this is Huge Mike cause a lot of us have been under the impression that since 2012, BMW changed the game and is able to monitor this.

No such thing as an original post/idea -) I do think it is reasonable that if you are going to upgrade software to be sure and upgrade other bits that may decrease the wear on your engine and chances of things going wrong (such as intercooler and charge pipe). NB* Didn't read the whole thread and see multiple people saying the same thing I just said. Not saying that a tune couldn't be uncovered (I'm sure it could) but it seems that there must be some other way they are picking this sort of thing up. So wouldn't the DME 'think' that boost levels were actually normal assuming the ECU itself was never modified. My understanding of how these piggy back tunes work is that they 'trick' the sensors into thinking boost levels, etc are artificially low and the DME then adjusts parameters to increase the boost levels. Routine servicing won't uncover it, but investigations into engine warranty work probably would. A 10 psi over stock target will look a little suspicious. Any tune is detectable if they look hard enough.
