Uncle Frankie,
Dyno it now while you're still running on SAFC2.
THen after you upgrade to E-manage, dyno again.
At least you know how much h/p increase.
If you looking for alternative source of buying e-Manage, try KSP.
THey can quote you price for e-manage + install + tuning.
KSP has alot of experience dealing with turbokitted engines running on E-manage.
