Yes, a good idea, but #5 and #6 on the early EZ's will kill your injectors, just a matter of time, plus your egt's get out of control real fast.
If you want to stack with a Smarty, leave the EZ on #2, #3 max. A better stack with the EZ is the TST (IMO), the EZ does the pressure and boost fooling, the TST does timing and duration and more boost fooling. Again, leave the EZ on 2 or 3, run the TST 5hp / 2tq, OR 6hp / 2tq max, with a stock CP3, you will be in the 450/500hp range.
Leave the stock boost elbow(for your wastegate) in, or your stock turbo will be short lived.
Have fun, Jess
