What car is this on? Year? I don't know what's with Lido's tunes but this is the second time in the last week I'm seeing someone post a graph here after getting tuned by him and the afr just looks scary. Not smooth and super lean.

Would it matter if my drag radials were aired to only 23 psi ?

What I'm taking from this is maybe I should go to a different tuner and get a second opinionWould what matter? That the afr is lean? No. That you had slightly low psi in the tires. If you aired them to 35psi it might post a few extra hp. Going from a 3.47 to 3.33 is nothing. That's only 1 step down. You added a bigger intercooler so need to force more air through it. As an example I have a V1 S on my Mach 1. Previously it was on my GT. Non intercooled with a 3.6 pulley and powerpipe it made 9psi. I added a Procharger intercooler and dropped to a 3.33. It made the same 9psi. Only gained an extra 5rwhp on the dyno. I then dropped to a 3.125 pulley and it made 12psi. Each blower is going to have its sweet spot. You might just have to go down to a 3.25 or 3.125. On my GT at 6300rpm the setup made 12.15psi. On my Mach at 6400rpm it makes 11.66psi and 12.4psi at 6600rpm. This is on a stock motor auto Mach with low timing.
What does your afr gauge show? A tail pipe sniffer reads a few points leaner than taking a reading closer to the engine. My afr gauge reads about .4 leaner than the shops tail pipe sniffer. So tuned to 11.8 I'm seeing 11.4-11.5 on the street.
I haven't installed it yet going in this year along with a boost gauge but the tuner uses an actual wideband not a sniffer

93 octane stock bottom
did just read through all my emails again tuner said that he leaned it out. Because he realized it wasn't alot of boost and that he Could get away with it and he said lean is more power. Just concered that that much leaner than last year only equated to 16 hp
