Hello,
I have a 2007 Mustng GT and have to date installed a C&L cold air intake, brenspeed SCT tuner and 91octane tune, and just last Friday I had 4:10's installed to replace my stock 3:31's. Even with the new stuff, I still have very bad low rpm power. Once it winds up, it is like a rocket, but until then it is really doggy.
Can anyone help me here please? Do I need to call brenspeed and get a new tune?
Should I forget the tune completely and get a super chip?
Do I need to get it to a shop and hook up a dyno?
I would really like to get my low rpm's working like the muscle car that it should be.

Thank you in advance for your help,
Casper

What gear, MPH and RPM are you at when you have this "lower power" down low?

You tune should be fine, do not go looking to superchips or something.

I am in first or second. By the time I reach 3rd gear now with my 4:10's, I have the rpms up enough that it cures the problem. Thank you for the advice on the superchip. I have a neighbor that went with it. Can you tell me the pro or con's with using it.

Thank you,
Casper

I would call Brent about it. With the 4.10's power in the lower rpms shouldn't be a problem at all.
Superchips tuner?? If you have an Xcal, then i would definitely stay with that.
Also a dynotune is the best.
