Now I added CATTED EL Headers, and it is still SOOOO fkin raspy, even more ridiculous. I'm pretty sure it's not a leak, I bought new gaskets, replace the old ones, although the new gaskets were all OEM. In addition, I don't hear any hissing or fluttering or ticking either. I thought that getting catted would make EL not as raspy, but this tune makes it very raspy. When I look at other people's set ups , theres are NOT raspy because they got an ECUtek tune. |

I was just looking for the header on the OFT site today and it's gone. Google search show it, but it's a dead link
It was just there a few days ago... anyone know what's up?

Interesting. They don't show a header for any make on their site now. It isn't just the twins they aren't listing them for. Must be out of the header business.

True. It's been wonky ever since it was revamped.

They only list OFT for all makes. No headers even mentioned anyplace anymore. Don't think that is a site issue.

nikitopo, Tcoat isn t the only one saying that refining the cam timing for a "standard" header with normal/short tube lenght isnt giving much gains. And it s true, there s not much to gain, cam timings tune is more efficient with catless long tubes header
what you gain changing cam timinga with your stock header, it s just because stock cam timings are inefficent and more towards fuel economy/valve overlap/EGR but you have a locked tune you can t try it by yourself Last edited by tomm.brz; 05-05-2018 at 05:50 AM. |

The cam timing is tweaked to work with the scavenging characteristics of the header be it long tube, short tube etc. There are obviously other considerations but cylinder filling and exhaust scavenging are biggies. I really like my ofh and oft. If I someday need more power, it'll probably be time for a different car.

what i meant, is that if you could modify your tune you could try other cam settings and you could feel that actually if you make small adjustments, you won t really feel big differences of any at all the reason your cam settings are probably not aggressive (like stage1 tune) is just because you have catted stock header, if you run stage2 or stage2+ you encounter more knock easily specially on high rpm tuners dont give usually a f*ck about emissions if you need to pass emissions easily you put a stock tune on or ask them or make yourself a stock tune with p0420 disabled if you have catless header in italy you pasa emission test with catless header and stock front pipe, that s for sure cause all my friends passed that way that s for pre my16 car, maybe euro6 emission check ia more difficult |
