I have a haltech on the way, Im also swapping my car to a manual. Pretty much everything is getting redone under the hood. I will be running premix. I have spent hours searching on this subject and havent produced a whole lot. What can be removed? What has to stay in place? Any common tricks or writeups available? Like I said I have hardly found anything. There is a lot more available on going bareback with the FC. Thanks.
