06 Mustang GT Issues - CIA, SCT & Underdrive pulley

[daveb1]

Purchased the following:
Steeda CIA with High Flow Elbow
Steeda Throttle body spacer
Steeda Underdrive pulley.
SCT Tuner

Installed all parts to spec. Flashed computer with SCT. Now car is throwing check engine light.

Car is running really rough with no power, idling rough, feels like timing is off. Installed Steeda tune for 93 octane. Not sure where to check. Will pull codes today, but wanted to see if anybody had any tips on how to make my baby run better. Everything was cool till I messed with her. Recently had her serviced and replaced fuel filter. 

Plan is to do the following:
Check all connections and make sure everything is installed correctly
Reflash Computer with SCT/Steeda tune


Hope it works. Any thought on this would be greatly appreciated. I'm no mechanic, just a simple computer salesman. Look forward to any replies.

Also thought I'd ask about how this tune would impact State of MA vehicle inspection? We are close to being as bad as CA. They plug-in to PCM will the Steeda SCT tune throw up any flags?

Update - Checked codes for Check Engine light.

8 codes posted for Engine too lean.

Cleared codes and reflashed to stock program. Then re-flashed for Steeda tune. This worked great. Car ran really good, but still putting up check engine light.

Any thoughts on what might be causing this??

if you are getting lean codes, either the tune isn't loaded correctly, or something in the CAI isn't installed right. Are you using a tuner that was pre-loaded by us?

Just wanted to say that Steeda Rocks.
Found my issue. Car is running great and the power is incredible.
Steeda Steve thanks for the support. So glad I upgraded with Steeda Parts.

Turns out problem was operator error on my part with the SCT tuner.

Glad we were able to get you up and running right!
