LLY: Rail pressure?

[05chevy]

How far have you guys pulled the rail down and still made good power. With stock cp3. I'm currently pulling it down to 20k. I have pulled it down to 18k before and felt real strong and did great in a few sled pulls.

Just curious of what guys have seen. Trying to get the most out of the truck this weekend at a local event

You are hurting your power at 20,000 and below

The truck has always pulled rail down to 20k. From my completely stock 12.35 passes and the 11.78 pass i made a few weeks ago. Lower pw and higher rail never helped with my E.T.

Get it to hold desired rail on the same pw your runnin now thats causing it to drop and ill bet you see atleast a decent power increase at higher rpm
