Ported TB tune?
Trending Topics
My idle is ALL OVER THE PLACE and yes.. everything is good with it and no issues installing it.
It will go from 700 to 1400 when in neutral at a light.
and then back down. car just revs and stumbles and threw a code after install.
I have been driving around for about 3-4 months like this lol.
But I NEED a tune
it was an S2 Shaner on my 2001 Camaro SS

edit - wyckedcamaro.....that sounds more like a physical problem then a tune issue. i've ported over a dozen tb's and i've never had one do that. mine have never needed to be tuned for either to keep an idle.....when it goes all over the place like that you blew your iac sensor or you have a seal issue with the blade.
