I was just wondering what mph, to have my converter lockup at?? Right now, its at 89mph...Do ya think I should lower it to say...75mph?? Would it help produce better ET's?? Any disadvantage come from doing this?? (engaging sooner)?? I have a Midwest 3200, and my 383 LT1...(3:73's, CC 306,etc)

 

ttt for me

 

I am not real familiar with the control algorithim for the A4, but AFAIK it won't lock up at all until you hit high gear.
