Thread: HV3 insert installation help

read the whole thing, the 15 whp power is 6000+rpms. like i said you need a tune so you can atleast rev higher.
but drive it for while, your pcm need to adapt the best it can for the extra air. I had a tune already before i got the hv3, i got the hv3 and went got a retune and overkill said i was running lean so he added extra fuel and timing io noticed a good jump after he was done, just keeps pulling harder now.
thats even after my first tune....so thats why i say TUNE TUNE TUNE makes or breaks the hc3 experience.
