The point of this thread is to compare dyno tuned charts to compare low, mid and top end gains to benefit helping us all understand where power was made and using what mods.
if you would like to share tuned calibrations to benefit others understand what different settings affect different motors. just to clear things up no 2 motors are alike and calibrations should not be used without tweaking to your specific setup.

needed mods list:

Motor: k24a2, k20a2, a2, a3 ..etc
Header: DTR 4-2-1, hasport, toda ...
Cams: stock, itr, ips, crower, toda ...
Intake: if custom then especify
exhaust: all details and size from header back
Tranny: specify which and FD
Misc Mods: TB Boring, IMG..etc
Track info: 60ft / 1/4mile times if available, especifying vehicle chassis, weight and tires used.

PLEASE POST DYNO CHART IF POSSIBLE!

Care to elaborate on the exhaust? or was it open header?
Looks like you wrote 3 foot custom cold air intake.

Quoted from: "toda pwr"

Last night, the car went [email protected] with a 2.041 60' on BFG drag radials. Some guy let me borrow the BFGs and they were completely bald. I was hesitant to run them but more desperate for better traction.

Correction to my earlier post. Found a mysterious set of extra cams in the shop andfound out they belong in this engine. Not the ones that are in it. Oops! Also switched back to the stock intake and it made a few more ponies.
