The quickest and most cost-effective path to 350-375whp on an 05:
- Warrtalon stg1: BR TBE, Forge UNOS MBC+gauge, Forge RS BOV (recirc), Walbro Fuel Pump (tune now or later, depending on how much you do at once)
- GSC 272 cams
- BR LICP
- BR coated SS o2 housing
- SMC Alky Injection
- Custom flash
That's all you need. I wouldn't bother trying to hit 350-375whp on the stock turbo with Cali 91pisstane, thus the alky.
