Hi guys, I just got my baby back from a mechanic for BHG surgery. Well here is the problem, I notice that I have little or no boost all the way up to about 2500 - 3000 rpm. I see a whole lot of vacum but no boost. I have a T04b 60-1, Hks DP, and custom hard pipes with a spearco I/C. I am using an AVC-R my wife got me for christmas last year. It was fine even after the gasket went running at 12 psi. I have checked for boost leaks but I have not found any, I had to redo the vac lines so they are all new. What could be the problem, before the bhg, it would build boost instantly but now I really have to get on the throtle.
