Default 700 Sci Whipple Upgrade

Ive done a fair amount of research on here looking for some answers on the Whipple Stage 1-4 upgrades for the 700SCi and most seem to be pretty positive. I have a 42' lightning with 700s and #6's, and while I know the NXT trans is the weak link in the system, I'm ready to pull the trigger on one of the kits and I think I've talked myself out of the stage 4 at this point. Anyone who has done stages 1-3 have any regrets or issues wishing they would have stayed away from the upgrade entirely? or has anyone done the stage 1 and wish they had done the stage 2 or done the stage 2 and wish they had done the stage 3? I'm leaning towards a stage 3. Thanks.

If you go with the whipple upgrade make sure you also go with the Hardin water pump upgrade:

Even stage 1? I see stage 2 has the bolt on water pick up and then the stage 3 adds the billet flame arrestor.

I have stage III and recommend it. EVERYONE talked me out of doing stage IV, including companies that would've made money off of me upgrading. FWIW.

These are going in a staggered 42 next week. Should be a slight change from what it was with the 700s. Motors make 1030 at 6K.
