I had a CPT65 (Turbonetics ) From Cotton on my car in the past with 009s.... stock longblock , there is more involved than the turbo it depends on the rest of your combo along with said turbo and what boost levels your palnning to run , i ran the CPT65 up to 27-29 psi but i also ran it that high on C-16 only which is going to alow you to get leaner w/o problems
