Yeh carbs are the reason for me going EFI. I got twin SU's after the A12 I had with the same setup. It worked mint!!! I got 200km/h out of the A12! I was looking for better results with my A14, little did I know SU's are difficult to get parts to tune them and then it's hit and miss with needles. Bugger that!!!! Since I had the quad throttlebodies on I haven't looked back. Even when I didn't know that they don't produce much vacuum and even when I was getting 14L/100km I didn't look back. Now I'm running Megasquirt and my economy and power are up and throttle response is GREAT!!! EFI For The Win!!!!!

Tuning on the fly is so much easier, oh its running a little lean on that corner..... adjust there and fixed!!! Easy.

I am not a tech who has done a course, nor am I a rich mofo who can buy the planet with daddy's money. I have done it the hard way all myself except my manifold which a mate whipped up for me. EFI is much easier to learn than mechanics, there's no hit and miss with electronics, only precise measurements that work time and time again.

As for the EFI A-series, Mine sounds mint with quad throttlebodies!!
