ok im getting a ts chip I have a boost gauge, egt gauge, Napa 6637 air filter, 3" down pipe
should I get anthing else to go along with the chip such as a boost relief valve?

 

The TS is good but the hydra is better. No you don't need anything like that

 

so I wont get overboost light on dash?

 

There is no light that comes on for over boost. If you go over 30psi it will defuel you. But with stock injectors you will not make that kind of boost

 

I have similar mods and the only other thing i'm consdering is buffing is my trans. If you're running stock E40D trans make sure you've got good fluid at the proper level and consider a better trans oil cooler like something fan driven.
