thank you guys !! you did a great job in a record time ... the car was up and running in a total of 3 days ... I figured out why the car was backfiring when we first started it... dealer in Japan put new NA plugs in it by mistake !! I think I told you .. boost controller is also now working great ...
The trouble with doing something right the first time is that nobody appreciates how difficult it was.
