Thinking of upgrading my Throttle body to a bored out unit...I am not sure which product is the better of the two...The price is about the same...Can anyone help out with an answer between CFM Tech, and Turbo City products??? Thanks for ant help provided....Tom

 

I'm not sure if one is better than the others but there are a few more too. XtremeFI, Holly 670 TBI, and the 454TBI are other options. I would imagine it wouldn't be necessary unless you did major changes like a cam and head change. From what I understand a larger TBI unit isn't really needed until you hit ~300HP or so.

 

Well thanks for the reply...Im am going to find out if it will help...I needed a new TB any way as mine was leaking a tad around the bushings...I have done just about every bolt on there is that is doable...(at least I think so)...I ordered one from CFM today, as Turbo City no longer carries one...Will also put the pressure gauge on at the same time as the new TB, new Injectors will be included in this swap.....It will be there when the engine gets upgraded, if I ever get the money thing right...Once again thanks, and I will let all know if there is any difference no matter how slight...Tom
