15 hp is not a gain so you could not see any improvements. Low fuel octane can negate 15hpYea I've checked with multiecuscan, all was fine.
Well I've contacted squadra tune, they say the "gain" is only 15hp and 30nM which is silly to me, but even if that's true, I should run better times than stock.
Da was 1100m, temperature outside was 34 celzius, and was 60m above sea level. Don't think all of that would slow me down for an entire sec, which people are running with a tune...
