Ok, so here's the deal.

Installed the BBK TB and followed the instructions to a tea, so far no problems. The only problem is, on a cold crank start, it idles at almost 2k RPMs for a few seconds, drops to 1500 RPMs and then about 1200 all within 10 second period. When I throw it into Drive, it drops to 800 or so.

I do have a BamaChips 93 Race Tune and Doug included the BBK CAI and the TB in this tune.

I'm thinking it's either something I have to set on the TB for idle, or something in the tune? I am leaning to the tune. I wonder if something has to be tweaked?

If I have to, I would go to Tillman Speed and see if they can diagnose and fix this issue I'm having.

Any thoughts???

 

Just my .002, but I've heard nothing but problems from the BBK throttle body.

 

Have Doug put your cold start values back to stock.

 

BBK T/B = problems

 

That's not throttle body related. Give me a call!
