Elephant and Admiral were cheapest for me. Without the remap the insurance was only £440 which seemed pretty good. I checked the ecu/chip mod box and admiral went up to £490. Again, not bad but it seems the box was only covering a 10% increase

hit the correct box once I get to the admiral website and the insurance jumps to £691

for 12 months and £590 for 10 months. 26 here with 2 years no claims.
The car looks identical to your as well mike.
