Heres the results of the 4495 headers, good exhaust note, smoooooth acceloration and a strong power gain.

Last dyno at C&V it ran 174 rwkw with the old header and the same tune as you can see its the headers that have given me all the gains. :spoton:

Got word today that the High out put Coils are on there way soon.

BTW the old 4490 coated headers are still for sale.

Nice healthy gain there mate, more than I expected.

Your car seems dangerously lean at the bottom end though. Mine starts off rich and leans out steadily to max power. Adding extractors and exhaust leaned out the whole range and flattened it a bit but still the same shape. Yours does the opposite so Im wondering whether that is the TB, tune, extractors or some combination of all 3.

I knew we wouldn't see power in the 190's but Im very happy with todays results.

200 rwkw is very much in reach now so Im going to push on with it.
