DYNO - NISMO CBE and K&N Dropins

That's some nice gains on a budget!

What surprised me is that on the graph it shows the car got richer with the K&Ns vs. without. I'd have expected the opposite, but maybe the MAF system adjusted for them and added a bit of fuel.

That's just the WB stuck in the tailpipe, so not really accurate.

I will try and get the data logs from Dan @ OPS and post them.

But it was stuck in the exhaust for both runs correct? Still relative I'm thinking as it'll read a few ticks leaner at the tail pipe vs. pre cat.

Or maybe the car haden't adjusted entirely and was trying to compensate for the new filters since it sounds like he switched them on the dyno??
