My son had his van tuned by altering his ECU, on his van it has made a big noticeable difference, it has been tuned so that it will still be reliable, I haven't noticed anything like that for the Roadster, also would it be worth it.

NA tuning will give you a bit of extra power, most people get a Power FC (standalone ECU) or go with a piggyback unit like an E-manage ultimate, you will get more gains out of a remap with a turbo, gains on an NA car aren't great - guessing your sons van is also a diesel as modern diesels remap really well.
Check the below thread for examples of what others have got out of their car NA:

Anything turbo or turbo diesel will see good gain in both performance and efficiency.
They leave a big margin for error in the tune for dodgy fuel and bodgey maintenance.
NA engines isnt really worth it.
My sons van is a turbo diesel, that's why he noticed a good improvement I guess, not really worth doing to mine then, mine is bog standard.
You can't tune/remap the toyota ecu. You have to go for an after market solution and then tune it. It gets expensive very quickly with very little gains on a standard engine.
