I'm running stock weights with 4.5 g riets in all 3 holes on each weight.Primary spring is changed to stiffer spring,Blue pink blue or blue silver blue.they are very similar.Stock helix and secondary spring is in the stock hole location,if you over rev relax secondary 10\20 degrees (1 hole).Also change your rollers in your primary from 16.5 to 14.5 this makes a huge diffrence and must be done.
hope this helps.
I run a mpi supercharger @12lbs boost and LOVE IT!!!!! Hate to say it but there is no going back to a stock sled EVER. Also run an A/F ratio gauge at around 11.5 to 13.5 to keep it safe.
