Software upgrades:

Rev limiter is set at 7300rpm since the head is stock. Turbo 28RS has 1.8bar max pressure with use of WMi and 1.5bar for use of 100oct fuel.

3bar map sensor is needed since OEM map sensor cannot manage load above 1.55bar.

With a lot of R&D to the variable valve timing, we managed faster spooling whereas peak power is exacly at revlimit (7300 rpm).

Use of 98/100 octane fuel is mandatory.
