Most people go for stage 1 then 2 which is a 3 hour session job done if the car is healthy etc.
I ideally want a custom map as I want my bigger injectors and bigger maf added, However I cant afford to leave the car for a week because of my job atm. Custom map is week long.
So AGU with k03s and forge actuator and yellow spring
forge 007p yellow spring
3inch turbo back with decat
THS front mount intercooler
5 piece silicone boost kit
Creation sprts tip
Catch can
The above is ideal for stage 2 on AGU but if I add my Calibra injectors and VR6 maf then a custom map would be needed as im pushing more air and fuel through.
