I had the Dinan Stage 2 flash on both my '07 335i sedan and my '10 M Sport LCI 335i Sedan. Both cars had the N54 motor.
I can confidently assert that my M Performance Power Kit-equipped F30 M Sport 335i feels every bit as strong as my old Dinan-tuned N54 335i sedans. One difference is that the BMW tune feels a bit smoother and more refined. To me, that says a lot because I absolutely loved my Dinan Stage 2 flash. I enjoyed the Dinan Stage 2 software so much that I paid for it twice because both of those cars were leases. 
Side Note:
Now that there are multiple tuning options available for the F30 (and there certainly will be more rolling out in the coming months), there will be an increase in debate and discussion regarding the merits of each tune.
We absolutely want to see thoughtful, lively, and in-depth debate regarding the various tunes that are available for either the N55 or the N20. That's what the N55 Turbo Engine/Drivetrain/Exhaust Modification sub-forum is for, after all.
That said, there will NOT be a repeat of the tuner wars that occurred back in '07 when the N54 made its much-heralded debut. People have different wants/needs when it comes to choosing a tune. Some people want maximum power, some are more risk averse and are content with less power (knowing that there is absolutely no possibility of any warranty hassle), and some people are willing to pay $X whereas others will only shell out $Y . . .
Bottom line: You can have a difference of opinion regarding the available tunes. And you can openly express that opinion.
Just respect another man's choice. You're simply not going to convince someone that your tune is better and that his is worse because ultimately, what is better is subjective. Impossible you say? How can you argue with dyno runs and slip times? "That's hard data and the numbers don't lie!"
My response: It's simply not solely about the numbers. As I've made clear, other considerations, aside from raw data, contribute significantly to someone's choice of tune.
I've stated elsewhere that the only track my car will ever see has left and right turns. My car will see some time as a daily driver, too. I don't need to be the fastest car on the road because the fact of the matter is, there is always someone faster.
Carry on.  |
Someone just please dyno the damn PPK already so I can see the real numbers. the 20hp/38tq or what ever it is, is definetly underrated. I need to see some numbers to the wheels.
I agree hp is not everything. Ive seen 425-450 hp cars beat down 500 hp cars because they cant put it to the ground. I was that guy with the 572rwhp car that lost to a 440rwhp c6 because the car is a feather and the guy knew how to put what he had to maximum use.....
Of course the higher the gain in hp the better the selling point. Not bashing any tuner but its a great selling point...my pee arch is higher than yours.
Dyno king and queens. Like my car below. Shit ton of power but it had its limits of what it can put to the pavement..
