Does anyone know how to adjust this and make it hold boost. I bought this brand new and I can't get it to hold boost. I adjust it but I keep getting 15 psi. I have it adjusted about all the way down. I'm thinking about taking it back and use my refund to help buy an apexi avcr. I should have got it in the first place, but honestly I was kind of scared of how hard it would be to program. I guess I'll just have to stop being scared. If you have any helpful info don't hesitate to give it.................lol
