Sterling exhaust jetting P2

I have put a STERLING BSAU193AT2 Exhaust on my Mk1 P200E, shall i change any of the jets, they are standard at the moment.

I think i have lost a bit of top end speed, but acceleration is good.

Increase your main jet to 122 or poss 120 , do it soon or you'll be burning a hole in your piston crown ! [+o(]
