When i finish qualifying and i did an extra lap so i finish in 5.16 or something halfway of the in-lap the engine stalls.

With wide open tracks like 301 your in the the throttle alot!! The 2630 will have run time issues with large flowing tracks, and as a whole uses more fuel. In fact ....it probably uses more fuel that all the other pipes. It also makes alot of power. With smaller tracks where there are a lot of corners and you are in and out of the throttle a lot the 2630 may make runtime more easily, but it still will have less run-time than some of the above mentioned pipes.
