30% is 69bhp, so the DTUK one adds less than this.
That's true but a member on here told me last night that new files have been released for the DTUK box. Perhaps it generates more power now but that's pure speculation. Esure are not mod-friendly at all so even if it is "only" 30%, I'm sure they'll make me bend over for the privilege.
When your insurance is up for renewal just go somewhere else.
