that depends on your tune and which octane you use

Generally speaking 460-490 wheel BUT you are leaving out some very important factors imho, building power is easy making it useable for every day use, dynamic, predictable and reliable is where it gets hard and only a select few really shine. You can make great power for a weekend, brag a little on a forum or IG and then blow up your motor on Monday if you're not careful.

Even though you are running a flex fuel sensor, that's not going to address what you actually plan to run in your tank (e30-350) on an otherwise stock car is probably ideal. And most importantly what is your and your tuners tolerance for drivability and engine reliability and how do you balance those parameters with power gains?

All things to consider and every tuner has a different approach and those approaches range from ultra conservative to down right irresponsible and reckless. Most of us want as much safe drivable power as possible but want insurances that our chosen tuner has not stepped over the line.
