Yes, as long as your system is tuned for up to the highest airflow reading the MAF will see, lower boost levels will not need additional tuning. You wouldn’t want to dyno tune the car on say, 7, on the dial and then decide you want to run the car at 10 since your tuner wouldn’t have seen what that additional airflow looks like in terms of fueling, timing, etc. I do like that with the Smoothboost, if you make changes to your setup, you can start on lower numbers on the dial to make sure all is well before dialing up to 10…all without changing pulleys.  |
Thanks for the info. Maybe I misunderstood in regards to the duty cycle on the injector. SAM at AMP mentioned that at the 780 HP level we were MAXED out with the stock injectors on E85 so that's the reason he backed it off a little. I have no doubt as well that we would need more fuel delivery from the fuel pumps if were to go beyond this HP level. We are running a 2.40 upper pulley NOW and originally used the 2.30 upper pulley.
