Best thread of the day... friday funnies a little late?

Tune is the best advice.

But here's another tip... after slogging a track car around with 3.9 gear ratios for so long, I am a total dickhead for not changing up to 4.11's sooner! The car has come alive and I only run a VF28.

Turbos with P18 housings very well suited to 4.11's. I'd imagine 4.44 would help the laggier P20's similarly...
