Question for large TB owners ???
I just installed a Lorenzo 60mm TB and matching 60mm adapter. This is a beautiful piece of high quality and fit perfectly. My car idles at 850 rpm as stock. Off idle - low end - mid range throttle response is great. I drove the car about 20 miles and at the higher rpm range it feels lean? I have Stage 1 and my boost spikes at 20 with my Stage2 WG and then settles lower to 16-17 lbs. I reset my PCM by disconnecting the battery cable while installing the TB. Does my PCM need time to adjust to the increased air flow and give the engine higher fuel flow? How long until I feel the benefits of the greatly increased air flow to the engine? Everything on the install appears to be perfect but top end power is lacking - in my opinion - due to not enough fuel to go with the added air.

yeah the lfs 60mm tb does lean things out a bit. You need to compensate for that somehow. My suggestion would be to turn the boost down, or add more fuel. As it is now, 18 spike, drop to 15 would probably be better for you, unless you add more fuel.

Also, I am getting rpm float around 1600 and up to 2300 when I let off the gas at times. I have had the tps sensor and harness replaced, but no change, and I assume that it is the tb.
Should I get tuned at a shop? Are we risking anything?

the s2 set up is fine with fuel. s2 runs so rich you really can't even believe it. we dynoed my car after the tb install, and the a/f was still off the charts rich. don't worry about it, you're fine!

What about running in HOM, black dragon? I'm in Hom a lot. I have the same s2 w/toys setup, with an aem sri, 3" catless dp,denso itl20's, and borla exh. I spike to 18-20 depending on the heat, and hold around 17-18 to redline. I am popping, afterfiring, and burbling an inordinate amount lately, more so, since I put in the tb a while ago, and I am wondering if I am in the "danger zone" at all.

And you should be fine, you have more than enough fuel...
