Post mod questions
I added the following mods to my car starting with the exhuast and working my way up to the heads and intake which were just completed and had a few questions. What should my fuel pressure be with the larger injectors? It is an auto and wondered if i needed a shift kit and if so what brand and type? It has 3.07 gears and i was thinking about going to 3.73's and had heard of whining being a bad issue with changing the gears. The mods i added are listed below. Any advice would be greatly appreciated!

You def need gears with that.
It will only whine a lot if someone installs them wrong
If they did make a tiny bit of noise you wont hear it over the car anyway
Should make a solid 350+ at the tire there.

its not that big a jump really. Youll notice a slight difference in normal driving and cruise rpm but if that gear is matched to your mods on WOT it will really move out like its supposed to. Thats when youll say "Ok this was the right thing to do"
Gear it for the cam not for a desired cruise rpm it be what it will be.
