Otherwise I'm sure he would likely be running the PROcede or JB4 as it potentially has more power currently (assuming AFR were to his liking).

I could be way off but that was my interpretation.

I personally think the misfire problem might be inherent internally, I.e. valve lash or cam noise or something, or it might just be a faulty sensor like crank sensor? Not sure if those were checked or changed out yet. Little OT.

Possibly, however there's a BUT there...

I'd still personally prefer to run COBB or a high power flash tune though as IMHO it is a far better/more predictable tune than any piggy on its own, this goes solely on the fact that after having seen boost/timing and especially AFR logs and fuel control be dead on from one pull to the next and the plethora of logging channels on it it just can't be beat...as themyst said once, logs on COBB are almost boring to look at given how consistent they are from one run to the next...

I just can't wait for ATR, period

Post 34 sounds a little odd to me but let's just sing kumbaya at this point.

Yea I figured as much.

still on that same act street clutch?
holding up well at these power levels? How many miles do you have on it now?

[dzenno]

Tons of pulls on it, a bunch of hard launches and some no lift shifting, the thing is doing just fine..about 20-30,000km

Forgot to say, is 471whp the new pump gas dyno queen?

[blubyu]

What were the SAE numbers? This time of year depending on where you are located could add close to 20rwhp for cooler weather alone uncorrected.

[dzenno]

BMW community never uses SAE as it doesn't give us enough mojo lol everyone uses STD which in this case was the same as uncorrected...in any case uncorrected has been established as the number to use as it is the actual power the car made in those exact conditions on that dyno that day and time...

Man this website is weird lol. Piggybacks are still worshiped and STD and UNCORRECTED is the standard. West Coast guys are screwed when it comes to bragging rights I guess.

I know UNCORRECTED is the actual power on that day/time but these internet bragging right "records" should be measured with a standard correction factor (SAE). Go make 471rwhp UNCORRECTED in Utah and I will be impressed

[dzenno]

I know eh? it is what it is, fwiw SAE correction for the 471 uncorrected run was 452whp SAE..

In any case, I just checked around a bit, looks like it really is the new pump gas n54 dyno queen lol

450 rwhp is stout as hell for a bolt on tuned car. I know I won't have mine much longer but I will be curious to see this motors progression over the next 3-4 years.
