Thinking about both fitting a crd2 box and upgrading my injectors to get things flowing a bit more on my treg 1.7td. Will this present any problems and can the box be adjusted? Not really had a chance to look into the dtuk systems that much so dont know the ins and outs. Also, do the lambda sensors need adjusted/removed at all for any engine modifications? I dont mean to sound a pillock but my engine knowledge is limited to old bikes any help would be much apreciated. Cheers!
