Admiral were not willing to insure my car with a remap, they only said they'd cover it with a chip I'd done some reading and found that they wee fussy about this, so was very specific on the phone. When I called back to cancel thought the cancellations department said they would cover it but with a 60 increase on the last 3 months of the premium. Moving it to greenlight who only cover performance and modified cars saved me over 100 quid on what I was previously paying unmodified, so I'd definitely recommend giving them a try!
