34/18 gains and only thing changed was the runner length?

Very impressive results!

the cats were taken out also and 102TB was added with the custom CIA over the VR intake so its not a true apples to apples but seeing how it changed and smoothed the whole trq curve and the hp curve starts to run away at 4k plus is what tells me it worked i was expecting to loose down low some but it did not that i am pumped about

I have found that once you have timing within range, moving it 2-3 degress does nothing to power output. Only when you are far off MBT, would it be impactful.

If anything, you are better off with less, to protect against bad batch of fuel, hot day, etc...

Wcf= 1.099?

I would have expected it to be .9X% based upon a 40* night

These are standard runner that come with the intake I just cut and re shaped them since fast will not release the ask runner sets they have been teasing us with for 2 years now

I'm glad it made gains. Thanks for including us in on your project. If you ever drag race it then you'll want to shift it as high as you feel comfy for best performance provided traction, of course.
