Thank you friends for your replies.

After completion of lab 1, it allowed me to upgrade. First, I have quickly proed it fully. Previous max tuning was 353X. I took it to 453X with 1st free upgrade. Nitro is still locked but it is showing nitro speed @  29.9 km/h so I assume I'm on level 4. if that is correct, then I will be able to take this car on 5545-5555 without spending any tokens. It is bloody expensive to upgrade. Earlier, I thought I must have had maxed it on previous R&D in Mar'17 but looking at the required tokens, there is no way I could have afford that as I started my account in Dec'16. :)
