I getting 4.10 in 2 weeks on my auto and was wondering if Im going to need a custom tune to get the shift points right My pred will get the speedo right but was wondering if anyone has 4.10 with an auto and has any problems?
 
you just need that update on ur predator if its not already on there b/c when i uploaded the predator performance tune for my 4.10s my speedo wouldnt move at all...but after i got that update installed it worked fine

The only 'problem' is that the car will rev up so fast it may bounce off the rev limiter before it shifts. You have to experiment a little with line pressure (faster/harder shifts) and shift points. I set it to 5500 rpm.
