I think this is the way i'll be going once the headers go on. Good options and great pricing

Any idea of the hp/tq gain with euro headers and euro section 1? is the tune 'customized' to adapt for different bolt ons like a header? or all tunes the same minus the options?

I think they have different tunes for catted vs catless from what I could when I talked to them. Then they just add on options that you select on top of that.

Thanks Kwakjoe, I found them on FB and got some questions answered over msg. You're correct, cat and catless tune plus the options on top.

For those who have this tune, how is the power delivery with this tune? From what I've gather, flash tunes that are not done on the dyno can sometimes be spotty with power delivery. One of the things I love about the E46 M3 is how smooth the power delivery is.

It's actually pretty good. Whether it increased the actual hp, not sure, but definitely improved the acceleration throughout the entire powerband.

Eventually I'll end up going with Epic Race tune, but for now this tune definitely does the job for the money.

Its nice and smooth. I've only been able to put a hundred miles or so on since flashing but I'm impressed. The mapping on the sport mode seems to be pretty good too, not nearly as snatchy as the factory sport mode tuning but a total improvement over non-sport mode. For the price you really cant beat it.

Yeah, I should've mentioned, I've had it for about 3 months now with no issues. It's a no brainer if you're catless and are on a budget.
