Tracy has me sold on moving forward with CNC throttle body, Black-Iceolator (3/8") and I might as well jump on the RX polished ported IM, which looks bad a$$. Then I guess I'll need the Trifecta. Can't think of anything else after this, I'll be broke anyway lol

My 2012 LFX was on the dyno yesterday and made 270hp/232tq and the only mod is a CAI Inc cold air intake. My air fuel ratio was lean until it hit 6500rpms or so. Here's the dyno graph. Granted, this is just a tailpipe sniffer.

Not bad numbers meissen, seems to be better than many LLTs with just a CAI anyways.. I wish we really knew what the drivetrain loss on the manuals were. 323 HP with a 15% loss is 274 HP so if the loss is really 15% then it doesn't appear to be much of a peak gain, but if the loss is more than it is definitely a gain.

I'm sure it picked up numbers in the middle rpm as that seems to be the sweet spot for gains.

There are many differences between the 87 and 93 octane. Between my original dyno and last dyno was a good difference. The difference between a tank of 87 and 93 is going to cost you $4.00 more than normal to make your car run great. The benefits are in the long run. At the track I would stick 110 in the tank also and it ran fine. Hope this helps alittle.

DI engines run best around 13-13.5:1 na. It wasnt lean. 270 is a good number

You're right - what I meant is that it's lean in terms of what we're used to seeing on a dyno at WOT.
