Post Maf Tubes & Drop-ins, worth it??

It has to do with the shape of tank, location of the pickup point iirc. Basically, under very hard right handers you'll get fuel cut, usually it is just a hicup and then you're on your way, but depending on the lenght of the turn, level of gas in the tank etc, it can kill your car, pretty serious issue if you're on the track with other cars imo.

there's plenty of threads on this that will explain it better than I'm doing it lol.

Yep. You really have to be in the corner long enough to kill the car, usually it's just a hiccup that you can recover from. You can draw the fuel away from the pickup but there will still be some queued to get pumped through. If you run out of that and are still in the corner then there's your engine cutoff. I think there needs to be an element of forward acceleration as well since the pump is at the front of the tank.

yeah, it's usually happening in turns you are accelerating out of.

a lot of times you won't notice a mild starve. the car will miss, but keep on going...it feels a lot like vdc kicking in
