I feel like my converter may be too loose for my application. Dyno graphs are unlocked converter (red) vs locked converter (blue). One in MPH and one in RPM. The Red line represents unlocked and the blue is locked in both graphs. RPM graph (#1) makes it look lazy unlocked, but i feel its just flashing up around 5200 rpm. MPH graph (#2) shows the unlocked graph comes on much faster. Issue is it just blazes the tires as it spools straight to almost 500ftlbs. Would a tighter converter help this? Its a built 4L60e by Metro Transmissions in Washington and a YANK 3400 power adder series converter. Any help or thoughts and input would be appreciated. Thanks

 

Anyone have any thoughts? Or a different section to put this in?

 

What tires? What rear gears? Id say tighten up the converter to a 3000 or so. My car will eat up the mt 315's on the street from a roll if I try. My #'s are almost the same with the converter unlocked.

 

Dyno was with MT 275/50r15, now has MH 275/60r15. Gears are 3.50

 

What does the converter flash to on the street/track? Because most dynos are not loaded, it's pretty common for a converter to feel excessively loose and show lower power. I wouldn't get too hung up on it. Use it for the tuning tool that it is and get your data from the track.

On the street it seems similar. Flashes pretty high, and blows the tires off.
