Hello,
Getting ready to do some mods to the car, and I am struggling with which to go with. I have read a bunch of threads regarding the 2 and some reccomend the 18%, while many others go with the 23%. I have not had the car on a road course, but would like to at some point, but it's more likely to see a drag strip, and some autox action. Here is a list of the mods I have/planned.

CAI
Kooks LT 1 7/8 catless
Rotofab I/C Reservoir
ID850
New plugs and wires
Possibly 90mm throttle body
Dyno tune after mods

Any help with one way or the other would be great. Also, on the ligenfelter chart, it shows that you don't need an idler relocation for the 18% lower, then on the next line it shows you need one? Which is correct?

Thanks,
Travis
