The springs affect mostly part throttle shifting, the weights mostly full throttle, however, they are interrelated. Keep it simple and lighten the stock weights and try it out. It costs nothing.
I might buy a whole governor so I dont mess with the stock one.. so just shave a little off the weights I dont want to mess with part throttle settings at all it drives nice the car just shift wot to early.

That will be tough to do, try slightly heavier springs when taking some weight off the stock weights. That may give you the same part throttle shifts with more RPM at the WOT shifts.

If i take weight of just the weights dont touch the springs part throttle will shift sooner or later?

I just looked up the density info for both and right now atco is 88 feet vs 1000 for island. Thats probably it.

I double checked that. Google published the actual elevation for one vs the DA for island. Still. Atco is at 600ish feet right now and 800 with humidity factor. Still fantastic.

You need to get to Atco in late November, early December. On occasion you will get mineshaft air days where you’ll see -2000 DA days. For my car that was 3/4 of a second quicker than on hot/humid summer days.
