My post on this was turn or no turn( yes I did not look at what I was typing) and I ment do I need a tuner kit or not if I put the steeda underdrive pulleys on my GT :scratch: :scratch: :scratch: :scratch: On the last post I got 2 replies .
One said no and the other said yes

Anyone out there have any feed back on this

 

No, pullies have nothing to do with A/F ratios. If you are not changing the intake or exit of air/exhaust, no tune is needed.

We need a sticky or something that will answer these simple questions. Like a tuning FYI or something.

 

thanks
