Hi all.... it's early and I can't sleep cause I'm worrying about going to stage four.... lol

I talked with a good friend who sells aftermarket Scooby stuff and he took me out in his car and showed me delta dash (cool stuff IMO)

Here's what I'm adding to the car

VF 34
STI Inj
Fuel Pump
Remapped Stg 4 Vishnu Piggyback ECU

Here's what I have on it

Underdrive Pully
TXS Catless DP
Tanabe Hyper Medallion Catback Exhaust


I'm not the one normally to worry about **** like this but, for some reason after hearing him talk about EGT's and such and hearing about Subaru tranny's sucking... Kinda getting me worried, I do want to do Stg 4 and such, just need a little reassurance that it will be cool, also if you all can make recommendations on what else I could get to make myself more at ease about me not blowing my engine first time I take it out
Thanks all,
-Zac
