Well that's why I ask because you could be chasing something that really isn't there. You could just check power at your ECU during a pull as well. Does the belt squeal or smell burnt for you to think it's belt slippage?

 

No it doesn't look like its slipped or smell burnt or squel. I'm thinking we just have a lazy alternator

 

Have you ever thought about getting a kenne bell boost a pump?

I have this on my personal car running a constant 15 volts on a deatschwerks in tank fuel pump. Car made 665 whp, with plenty of fuel for more power. I'm using ID1000's, and injector duty cycle was around 80%.

 

Hey Bryan this is Cody.

I haven't honestly considered it but it might be something put into consideration for what we are needing.

We are right on the line as far as duty cycle goes so this might be the extra push we need, the. Again we are still running base fuel pressure of 43 psi
