is it me but i really think i can feel a big difference in my car it feels faster since the install of the 58mm tb, could it make that much of a difference? my mods are in my sig. also when i come to a red light the rpm's really fluctuate, they drop down to 500 then up to 700 then back down and then to 1000 were it feels normal what is this from???

 

I picked up 10 to the wheels from a stocker to my 58mm.

 

You need to mod the IAC to allow more air flow at idle.

 

how do you do that??

 

i assume the 58mm is only a good idea bc of your heads/cam?

 

it makes the car jump more at part throttle.

 

ok i did a search and found things like split blm's,etc... iam really confused i have an auto xray sitting in my drawer i need to learn how to use it.
