That, and they'll actually be easier on the motor. I'll keep the boost and torque in the (hopefully) safe range.
Look into 3.3 diff

i've played around with the different diffs and the 3.33 ratio is too high for use under about 7-800 wheel. id go 3.56 from 500-750 and 3.33 for 750+

With 18” wheels? I have the calculations which it says would work perfect and act like 3.69 on 19”’s

Wheel size doesn't change diff ratio just tire size. Are you running a Miata height tire?

Edit: with a 3.33 rear gear you would be running a 24" tall tire to get back to a 3.69 ratio vs ~26.5" tire stock

Boost by gear with Ecutek will change things a bit. Not sure how it will do but I will be trying that first before even considering a diff change.

What is the install cost on this?

Well the r&d motor is pushed way back into fall so it's hard to say anything for sure but it would be done as an ASSEMBLED short block
