I put my brown tops back in after a few months with the blue tops. Shifts are only firmer at low throttle. full throttle shifts are the same as stock. downshifts are harsh and blew out my brand new motor mounts within 2 weeks. Not a good mod IMO.
If the TCU can be reprogrammed not to shift harshly during downshift it would be ok. also, when dropping into passing gear on the freeway, the clutch is let out before the engine can rev up causing a buck - similar to a bad driver trying to downshift a stickshift.
