GRB BOOST UP STEP2...dump pipe and boost controller...

This time...chenge dump pipe to straight though pipe, and fit boost controller,heavy duty actuator to find  what can we get from this set up?

We had to modify dump pipe........different flange(*_*)""""

Try till max!!

This is the result.....gain power at whole range. The boost came firster as well(because of dumppipe and boost controller etc).  However boost came down at high rev(turbo size), also injector is almost max as well.

Next step??..... turbo and fuel pump, injector......... still ECU flash tho!!!
