My reasoning for thinking about wrapping my Y-pipe was to help the exhaust gasses flow faster.... not so much to lower transmission temperature.

I'm too cheap to have the Y ceramic coated... lol

Should have done ceramic coating. Oh well.....

Some codes showed up

 

[Chrismnj]

[Chrismnj]

Did you clear them, or did they clear themselves?

Cleared it self in city driving, but my feeling is they will comeback at highway speed BB needs to make some adjustments for A/F ratio, sent them my driving log after installation, waiting for updated tune

5th and 6th gear at 70-80 mph A/F sucks big time, very lean, gauge shows 11

Just go easy on it till you get the updated tune. If my memory serves, running too lean for too long, you'll burn through the pistons.

thats not lean? are you using a stand alone gauge or reading whatever is logged?

if your just cruising afr should be close to 14.7, wide open throttle with power enrichment (not sure if BBT has boost enrichment set up, not really needed) should be low 11s afrs

what did you end up doing for injectors?
