Shimming the Wastegate

[Isphius]

Its the same thing as using a manual boost controller. The boost controller would be a lot safer and easier tho, So just buy one for 20$ when you get a turbo. Shimming the wastegate just makes the wastegate open later (ie, higher boost). The fuel system can handle it fine. My turbo with some boost leakage will make 9 psi with the wastegate totally unplugged, and it handles it fine. The fuel system will be fine untill you hit fuel cut(11-12+, dependant on ambient conditions), and the stock ct26 can take about 12 or 13 psi. After than you need a lex afm, 550 cc injectors, and an safc-II or something to control the fuel. And then you will need to upgrade the compressor wheel. But to get to that in the first place you need a new turbo back exhaust, intake, IC pipes, etc. And a good FMIC never hurts either.
