I would say zero gains.

Thanks, Hutch. I figured it would be minimal at best. I tend to want to tinker too much trying to optimize my setup, but I'll probably just let it ride as is.

 

I always understood you want the RPM to fall back to torque peak or just below ?
So the RPM drop wanted would be less on a peaky torque curve Vs. more on a flatter curve ?

True ???

 

Something is not right with your combination. First off with that size engine you should not have to leave at 4400. Secondly if you are shifting at 7000 and the rpm drop is only 400 then the converter is way off for your combo. The leave flash as the shift RPM should be almost the same. When I ran a glide in my car it would flash 6200 shift at 8000. Fall back to 6200. Trap rpm was 8600 in the 1/4

 

I would let that converter in the car and let it eat. The reason it's only falling to 6600 after the shift is those 5.43 gears.

I shift at 6900 with a glide and RPM falls to 6300. With 4:56 gears. If I put a tighter converter in my car it will slow up. With a glide its all about shift recovery. I have a converter that is 3-400 tighter for my combo and it will 60 the same and lose ET.

 

Thanks for the responses. I am going leave it in and "let it eat" as you said. I have been really pleased with how it is running after a cam change this past winter but was mainly wondering if there was any gains to be had if optimized further. I am making more power hence the lower rpm drop on the shift with the same converter, while picking up 3 tenths over last year (6.80s to 6.50s now).

 

The converter will look better if you rev it a couple hundred more. It's about perfect for what your doing.
