Rebuilt 90 ls teg engine. Planning on the drag gen 2 kit, dumping the manual boost control...and running a tial wastegate, but which BAR should i get? .45(6.5 PSI) or .65 (9.4 PSI) ? If i get the .65 bar should i get piston rods? And I know i will have to get different fuel injectors. If i get different injecors will i have to get a different fmu? The kit comes with an FMU. Here is the URL for my kit.

some people are running 10 psi stock. it all depends on who is tuning it
