Never seen anything gained by taking timing out in high gear on an NA car and have tried on a few different cars. The one thing I have seen that ALWAYS works is adding timing in lower gears to base in an NA car. It has always netted quicker ET's....
IMO the Grid is much more use friendly than the old 7530, 7531 and 75301 box, but otherwise the results are the same. Just sold my last two digital 7 boxes to fellow members here
I know many years ago, John Hagen's Pro Stock car was pulling timing out in high gear. At the time he was running a couple MPH faster then Glidden. Glidden was the only one to figure it out, and asked John how much timing he was taking out? "I don't know what you're talking about Bob?" LOL.
Years ago, I once dropped the timing from 36* to 31*, to see if I could kill some ET. The car picked up over 1 mph, and went faster...
I bought one of those boxes from you Al. I know it fires the car up...
