ecutek can provide a stock base rom with vvt checks disabled eventually
it s dangerous if the timing chains are misaligned but if everything is in place, that rom helps as it turns vvt immediately on and can help relearn new initial values
actually i m running such a tune for 1 year, just lazy waiting for it to activate as i reflash often
