Dyno tune needed for manual swap?

[BR3W CITY]

Yes, you'll want a dyno tune. Bonus points if your tuner will take a ride with you to make sure it actually feels right on the road.

The torque converter in the auto trucks will soak up some things like small cam surge, which you'll notice in a manual car pretty quickly, even more so if its cammed or moving serious air. In general the "first flash" for most manual swaps (and even most manual cars in general) almost always needs to be cleaned up once or twice.

I'd say find a local tuner who can get you a base flash to get started (the gear values can be used to rough predict some of the speeds@load as you mentioned). He should be able to get you started on something that will allow you to start, run, drive and test the car as needed and sort out any functionality or mechanical issues right off the bat. Once the car is ironed out, you wanna get it back to the tuner on the dyno. That's where he'll be able to focus on performance and efficiency and actual net a gain.
