C63s w205- stage 1
Im looking to do a stage 1 tune on my c63s that will bring it from 510hp to 600hp.
most tuners gave me 580-590hp, so Im wondering if a stage 1 with 600hp is safe for my car?
claims it to be a tune from HCperformance.
wanna hear What you guys think about stage 1 with 600hp. Is 600hp too much for a stage 1 or safe?
