102 made more power.
And all this BS about drive-ability, sorry I don't get it (and never will). I tune my own junk, have for a long time. My fast 90/PTM95 drove like stock. My fast 102/PTM95 drove like stock. My current LS2/WARR92 drives like stock. If your car doesn't drive like stock, your tune is off, and it's probably not hard to fix. All current combos listed in this thread should be able to drive like stock.
Old photos to show you an idea

A 90mm / 92mm ported TB should flow ~ 1150/1180 CFM...that paired to ported FAST 102 or to a ported MSD 102 using a Velocity Ring should show no Manifold Absolute Pressure restriction until you cross 7500rpm or 670 FWHP, or is there something I am not aware of?

Thank you you gentlemen for all your suggestions. Except of course the few trolls that call names and break my ***** for no reason. 🖕🏽

And yes there are some TB's out there that we won't tune at our shop. Same goes for injectors.
If you expect your tuner to spend the extra time to tune your junk T/B or junk ebay injectors because that's his job and not get paid for it......get yourself HPT, learn how to do it and spend the extra hours doing it.
In the long run, if your tuner is charging you what he should, it will be cheaper to by good parts in the first place.
But this is the internet.......buy everything on Ebay....
ok i'm done now.....

So. For the record. My guy got me a 102 fast TB (instead of the 92 and vel ring) along with the 102 lsxr. I picked up 35hp and 30lb torque. Chilling right now at 440hp to the wheels . You all were right. It was a bitch to tune and it took him forever. Car runs well but can run better. Any idea how I find someone in the New York area to dial this ****** in? I’m having some pretty wicked rpm surges at idle and the rpms are just slow af in general in coming back down. They go up normal speed but seem to lag coming down. But when they do come down they chill at like 850 but then sometimes shoot up to 2000 and stay there. Need this fixed. I could go back to the same guy but would love to have some input if there are any people in my area that are awesome at this stuff. Thanks friends. Im pleased with the performance result but not the drive. Has to be fixed. 🙏🏽

You got the fast TB, not the nick williams or other? It used to be the fast TB did not fully seat on the body (air gap) and the iac port was too small (under 3/8 diameter) so it was a bitch to dial in.
Your IAC effective area table will require work to make it settle down. Just moving the whole thing ten cells to the right may help and is generally a good starting point.

I think Slowhawk can help get the car properly sorted out. He is also an LS1TECH sponsor.

I guess you engine is running Gen III PCM with 24 tooth crank...interested to hear if this lower definition PCM is able to deal with the requirement of a 102mm TB...

FWIW
The PCM's used with the 58x cranks and drive by wire are more powerful and much faster than the much older slower LS1 24x PCM's. It should be easier to dial in a 102 set up with the faster 58x PCM that can respond quicker to the IAC counts. Its my understanding from talking to several tuners, it's easier to get good drive ability and manners with the newer 58x PCM's when doing a 102 TB.
YMMV
