It is my beliefe that I have not been benefiting from the Boost as expected.

THis would explain how I was going through the 1/8 at 120mph (6.4)and only getting up to 145mph in the 1/4 (9.6/7).

I have also encountered more drama with this freakin thing

It either has a boost leak or an issue with the secondary injectors.
It's falling on it's nose around 5K RPM.

This project is so very frustrating...
