Bob after 30 years in the car business and ASE Master tech for 15yrs I wouldn't know where to start on putting a carb on a modern OBD2 Car. Dealing with your
restrictor tube is much easier. This spring we plan to tune our car on a chassis dyno with your restrictor tube. I will forward the dyno runs with or without the tube when we are done. Our tuner is one of best Honda guys in eastern canada and has tuned for teams that have won national road course championships. I'm sure he will able squeeze every hp out of engine with the tube. He is looking forward to the test, it should be fun.
