Hi All

Im after a bit of advice and opinions on which way is best to head. I have a bog std A+ 1275 with a HIF 44 originally with a K&N filter and a BCE needle which worked ok considering it hasnt been on a dyno to get set up properly. Im finding after now moving up to the hills its a bit flat from low to mid range whilst getting back on the throttle when under load. Have done the usuall things of playing with dashpot oils and giving the spring a bit of a stretch. So what im wondering is it worth biting the bullet and getting it on a dyno with the hope of improving the issue or would a pair of 1,1/4 SU carbs be a better bet for this sort of driving around hilly windy roads any advice would be great

I'd dyno it first.
