    Sorry to all the haters that wish it blew up, but she's quite happy. The low boost was caused by a bad turbo. That's why it was going single in the first place. I have realized that the DME pulls timing and closes the throttle well before MBT. So your all making much less power, than is physically possible. Oh, I heard Vargas's record is no more, too bad. lol. I did make 391whp with a stock n54 last week on a mustang Dyno. Whooptie doo! I also make 428whp with a stock k20a2@13psi on 93.

    ...DME responds to knock sensors to make corrections on a per cylinder basis to the timing target. It doesn't give two $#@!s about MBT.

    Not much more to say than this! I definitely wouldn't apply what I learned from years of tuning small and big block Chevy's to the N54!!!

    Timing pull is because of knock.

    Throttle closure is because of limiters you missed...

    With the throttle closures and timing pull, I was under the same impression. The next time I have a healthy n54 to play with, I'm going to load that advanced timing map back up with some new mods to the limiter tables/settings. I have only had limited Dyno time(4 pulls) with a n54 so far, so I played it safe and just started with the jb4 backend flash as a basemap. It made good power, but I think 16+ psi is way past the efficient area of these turbos. I saw iat's rising drastically and the stock FMIC isn't THAT small. It just seems like more timing/less boost would make more power, more safely.

    16 pounds down low is just fine on the stock frames. You’d want to taper it, of course.

    The stock front mount is terrible; there is simply no other way to put it. On a bone stock car requesting 9lbs of boost midrange, it’s inefficient within one or two pulls in all but the depths of winter. There is absolutely no scenario that I feel it’s appropriate for, from the core size, to density, to end tank design…it’s awful. The IAT comp tables are fairly aggressive as well, and will happily yank out timing if they don’t like the charge temps.

    You're on the right track. MBT seems to be somewhat lower on this motor than others I've messed with, but I've not confirmed that on a dyno though. Also, while certainly out of their efficiency range, the little stock snails are still making more power all the way up to 21psi. That's about the limit where most people stop. I agree that more timing less boost is definitely more efficient and safe on the tiny turbos, I'm not sure it'd make more power. I'm interested to see some of your testing though, if you're able to get some more dyno time. I'd really like to see some 16psi, race gas pulls with high timing and see if we can determine when MBT really is.

    of course they have. they're not sharing that information with other tuners though, unless it's in the form of an OTS map or backend flash. Tuning an N54 from scratch on something such as TunerPro or something similar is still a daunting task.

    I know for a fact they have. No one is saying this guy was not or is not a good tuner. But the fact that he thinks he can waltz into the N54 world, put a car on the dyno for 4 pulls, make claims that people who have done 1000's of pulls, and have years of experience are leaving power on the table that he is going to find is borderline insane.

    Tony, did you miss the part where this guy tunes honda Kseries? He obviously knows his $#@!. I bet he will even offer tuning packages that include an iphone jailbreak + hondata tuning for a package price, all from his fold out lawn chair at the parking lot of the car meet. $#@! yea!Click here to enlarge
