You have to weigh (get it lol) your options. Is it worth the lbs you'll save vs the hp you'll loose by removing it. For racing if you doing a lot of back to back runs with an almost empty tank it might be wise to up grade to something that would cool the fuel more efficiently. Think I read somewhere that diesel is its most efficient at like 150 F.
Yeah makes sense I would have to say I'm looking to utilize the space more than the weight savings. And yes the tank is always near empty so a upgrade might be in order.
