Hi, I'm interested in boosting my 99 Cobra, and had some questions about the Procharger setup. If I stay at 10 lb would I need an upgraded clutch or injectors? Is the kit with the Diablo tuner sufficient for conservative, reliable power? Is there a cheap, easy tuning option that would save money overall vs. the kit with the Diablo tuner which is $1000 more than without it? Thanks.
