Hmm, good info. Stock TB or a ported unit?
If you look at the multiplier for these tables you will find one of them is-1.6. This system has 2 humidity PIDS. Relative and Specific. Relative has no drive cycle attached to it. The specific requires vehicle speed for it to be able to generate a value. After you flash the ECM the specific pid will read 0 and with the multiplier factored in you will see 3-4* removed from total until this calculation has been performed. This could cause issues if not accounted for. My opinion is zero them out just as you did.
Is there anywhere in particular where you got the l86 intake manifold & the ported LT1 TB ? & also have you ever looked into or heard about anyone messing with they pulleys
I got my parts from Pace performance. I don't suggest a ported throttle body. Stock LT1 is plenty.
You only have to mess with the pulleys if you do an LT1 intake manifold or MSD. Best intake manifold out of the 3 is the L86 proven on a dyno.

Agree I just ordered mine but don't know if it is worth it on a turbo truck. I figure the throttle body being bigger helps but the manifold size make that much of a difference? I wanted to know if the l86 tb would bolt to a l83 intake? just 7mm difference but the bolt holes? Everything I read people said just let the truck recalculate for it, I'm sure that works but tuned is best as we see here.
The L86 intake manifold is completely different internally from the L83. The 5.3 manifold is like the older TBSS in design and the L86 is just like an LS3 manifold.
5.3 throttle body won't fit on the L86 intake manifold and you have to re calibrate for the LT1 throttle body.

Has anyone found a fix for the climbing/hanging throttle issue? I swapped an L83 into a Mazda rx8 and although it idles extremely well if I blip the throttle it'll hang around 2500-3000 for a ridiculously long time like some of the guys in here have claimed. I had to switch to the Camaro manifold and throttle body for clearance reasons so I can't really go back to stock. I have changed the manifold volume and throttle max area settings in HPTuners to match a stock LT Camaro and that made no difference.
All this has been tested in neutral so I'm resistant to even test drive it or drive it to the tuner.

I?d like to know this too. I?ve run both but don?t notice a difference. Can anyone explain their result of the higher vs lower number?
My assumption would be one would idle better right out of the gate. The reason the computer would want to know the maximum area would be to correlate airflow/torque for a given throttle position. At least that is my assumption. Eventually I would expect the throttle position to be learned and it may not make a difference. I would think with the lower value it is possible the throttle could feel a little more aggressive until learned - if it is anything to do with off idle.

Are these numbers from the l86 manifold and throttle body?
Or does this have the lt1 throttle body?
Clarification would be helpful.
