ERP, is that Ok to do for a T-7? (re wiring the hoses like that?)

If I only had a Saab buddy nearby to me who cold help me with this and let me borrow some parts for a test run.... I gotta now go hunting for parts I may or may not need, just to try this out? Man, this is turning into such a freaking project! this is just my luck.

You will only get base boost but you wont have to worry about fuel cut.
sorry, I am still a turbo newbie. What does that mean, that bascially the chip will not really be increasing boost? twhy not just go back to stock ECU?

Question; at 50% throttle do you only hit mid boost pressures or will it spike to fuel cut? I do not think that plugs or the DI is causing the problem.
at lower than full throttle the car seemed to drive just fine.
