OK so i dyno it and made 270whp and 200lb torque
Tuner tells me to bring it back after 1000 miles to put more power out . Is this true and why do i have to wait 1000 miles?

 

What type of dyno?
The engine should be fully broken in on the dyno. You should not have to wait 1000miles and go back and re-dyno.

For your set-up those #s seem a little low.
For comparison w/ the KMOD RSX we made 268whp-190wtq

i think they just wanna make more money off you.... im sure that setup will make over 290whp btw it'll be a good investment to get an aftermarket chain tensioner fro those bad boys

 

Excuse my ignorance but after a fresh engine build the motor is broken in on the dyno?? I would of thought a 1000 mile break-in would be a good idea.

 

tuner is kindda correct...assuming those CP pistons are street pistons therefore the rings are not racing rings, then you have to do a good 800-1000mile breakin after about 2-3 oil changes...typically it depends on the rings that you use, that determines the break in.

also during the 1000mile, the best breakin procedures typically for the street rings:
-dont keep at stead rpm on the hwy, vary it back and forth
-approaching stop light or stopping in general, keep downshifting to each gear and let of gas
-dont keep idling the motor

 

Are you a tuner ? where are you located?

 

did this car ever get redynoed? seem like low number imo
