Retune Needed for Throttle Body Mod?

[D-Cobra]

for those of you who have done the throttle body and plenum mod, did you need to retune your car? did the mod lean out your air/fuel?

also, what TB did you get? ported or single blade?

NO Billet flow

no

I did not tune after. I had it on the dyno and the air/fuel was fine. I went with the Accufab oval single blade b/c Billetflow was out of TB's.

D-Cobra, I would get it on the dyno to at least see what the a/f is doing.

On a side note: Your car looks awesome! Any more pics? How do you like the H&R race springs? Stock spring isolators?:beer:

I have seen a cobra go up 1 full point in A/F while doing a t/b swap on the dyno. I would dyno just to make sure. And come to think of it, he had just about all the same mods you did.
