shes a work in progress!

 

I would imagine say....18psi or so. I hope you have an aftermarket ECU, or else you aren't going to be able to do anything without detenation. Thats 18psi when you race, you should probably go lower than that when your daily driving.

Sport 550's should take up to low 20's on race gas without any problems. I would say you could do around 16-17 psi on the pump possibly, but I'd stay conservative on that side.

 

any news about that boost controller?
