When I had my motor done at KD, I mentioned to Dave I had a midpipe I wanted to install.....

He gave me some restrictor pills(Holley Jets) that he said to use when I was going to add a midpipe....What will these pills do?

Right now Im experiencing boost creep of about 4-5 psi.

Do you guys think these will help the boost creep?
Can anyone help?

 

I have a replacement pill in my car. I had to use it because my high flow cat caused spiking up to 15 psi. This is very bad with the stock ECU. I have what Trey Cobb (I bought the Bonez high flow cat system from Rotary Performance, TX) calls their 10.5 psi pill. It does work as advertised. I have a perfect 10-8-10 pattern with the new pill. The pill is meant to replace your stock pill in the wastegate precontrol (underneath the airbox). The orifice size is much larger than in the stock pill orifice. This allows you to bleed off more boost and prevent spiking and creeping. Hope others chime in since JSpecFD doesn't think I know what I'm talking about.

 

makes sence.....I hope to install the pills and check out how bad or better the creepin is

 

Do you have a boost control unita?
