U7193 WOT shift pressure

[Dave04SS]

I have a diablosport U7193 for my 04 Silverado SS.. It has an option for part throttle shift firmness (+25/-25psi) and a WOT shift firmness (+25/-25psi).. if i want very firm shifts should i raise them all to max? or is that +25 psi too high and cause damage? I raised the WOT shift firmness to max at one point for a little while and the 1-2 shift still seemed sluggish but better than it was. Any help would be appreciated.

it's not in psi... those adjustments are in %....

going to max 25% won't damage anything...

if you need/want more adjustment than that, you'll need to get a custom tune done...

If you want to improve your 1-2 shift opt for the 'Vette servo. Improves the shift and you can lower your pressure. You can find it on the net or eBay. Around $10-20. Only for the 4L60E series transmissions though.

definitely do the corvette servo. Or if you want they have larger aftermarket ones. I have the corvette servo and i kinda wish i had gone bigger. i also have my line pressure pretty high, i like living on the edge. Its shifts great.
