I'm asking this because i want to know if ít's proven technology and not a totaly new concept which could give problems.
The tuned engines are more like the new XXX Sirio, but with some hand tuning. The timing is different than the old Sirio Evo 4. The fit, and finish of the Capricorn engines are better than that of Sirio. This engine runs better, and has more power than the Evo 4 too.
