So I'm getting ready to run a bigger turbo in my 89 Spirit and I'm going to up the boost from the stock 10 psi to 17. I'm getting a ETG and fuel to air gauge. I'm a little worried though on the fuel delivery. I've opened the exhaust up to 3" with a 2.5 swing valve, and I'm thinking that the next step is to either get a bigger fuel pump and then an adjustable FPR, but still. What I'm looking for is some advice on when I really need to worry about EGT and what is the safest way to up boost and not put a hole in a piston. Thanks in advance for any help! <>< Sean
