MTM 420HP chip

[He Skunk]

Hi chaps (and chapesses) I'm a refugee from the Pork forum.
A mate with a RS4 (380hp jobby) was asking me if there are any durability/reliability issues with MTM 420HP chip.
Seems a fairly modest increase to me, and I remember reading favourable road tests in the mags a few years back.
Should I encourage or dissuade him ?
Cheers.

Thanks, I told him to come on here himself, but he is a lazy b@gger

Cheers for that.
