It's not necessary to do. I wouldn't do it unless you feel the need to waste some money. If you've got the $ to waste? I'll have them
I'm with brenx, no probs after its been running 30+ sec... Before I had my Proform main body, I had to chop the choke tower because of lack of clearamce between it and the K&N X-Stream lid, except i did it with a hacksaw, 4" angle grinder and a dremel, just hacked the tower off with the hacksaw and grinder, and then cleaned it up with a sanding drum on the dremel..... for me it made a big difference :D
Biggest hassle is having to plug the vac port that hides under all the choke crap on the side of the body... i got a tapered plug from a crab shop guy and hammered it in...
