Extractors on. Now what?

[Mitsi-undai]

Hi there. I have finaly got the Genie headers on. I was hoping for some kind of big improvment, as when the last lot went on I lost power.
I don't think these have evn improved my power.

At best I feel they are smoother. Maby there is a little more torque, but 0-100 time is still the same

I have now got the Apexi SAFC. What would you guys sugest? I have heard that extractors run your car a little lean. Is there any point I could just give it like 4% over whole rev range?

no real point,unless you can get more air or spark in...

so.....try this

Put on a K&N pod with a cold air feed and good long steel inlet pipe.Advance your timing to around 12-13 degrees..(if your motor can take it without pinging)
then add around 4-5% fuel.
I ran this setup on my GSR Galant.Good gains..mostly in resonse and torque.

**Make sure you earth the timing plug out on the fire wall when setting the base timing.**
