Thread: do you need to tune for a throttle body?

i was checking out zzp's stage 1 throttle body... it looks nice, do you have to tune for it?

The throttle body will not do anything for your current setup, though.

hmm well... im gonna have headers on the way soon hopefully along with colder plugs, and a 180 tstat n hopefully a 3.4 inch pulley. so what tb would work well with that?

The stock one.

i agree with josh here. the throttle body flows just fine until you get into smaller pullies.

and if youre that eager to get a bigger TB, i wouldnt suggest any of the stock ported ones. it's much easier to go N* or LS1 nowadays.

You'll need a tune for it. I ran quite a bit leaner with my HVTB Stg2...

x2 on the LS1 tb set up instead.
I had the zz stg1 and when i installed the ls1 with the 85 maf i noticed the throttle respose was better.
Never looked back after the intsall.
Do it and do it right the first time.

First of all if you're going to get a larger TB at all I'd go with either a N* or LS1 TB, and secondly you are not going gain much from a larger TB without a blower with the inlet ported to match. Your money would be better off spent on rockers at this point.

you could technically run it with out tunning but like stated above you will be runing a bit lean, if you can tune for it definitly do it.
