I couldn't find a "sharked" dyno with the A/F ratio on the bottom, but then again, I haven't heard anyone getting a "lean" code from it
i wasn't getting a lean code.

my car's performance went down after installing the headers. i logged A/F ratio during WOT and noticed slightly leaner performance in the midrange. that's where the biggest power loss could be felt.

so, i went back to eurocharged and had them re-do a tune for me.

i've had 3 BMW's now (135i, 335i, and my e46 330ci zhp). my 135i and especially my 335i made much more power (430whp on the e90)

i can tell you taht if you go catless, there are a lot of gains to be had by further tuning in the low-mid range. twin turbo engines are another animal, but even the m54b30 needs some custom tuning when running headers.

eurocharged doesn't get into BMW's all that much. look them up though. they have a very deep resume of tuning cars. the one in houston, by where i live, tunes Ferrari's, Lambo's, and a ton of Merc's.

they're just as capable as any other respectable tuning outfit, but my money's on them for the best flash options for e46's non-m
