MS3 Pro Sequential Injection + Coil near plug conversion thread

TB can be used for race as most of the time the car is running at pretty high revs ( look at an F1, the injectors are 6" up the tunnel ram) but off idle as stated will be 'dirty'. Also mpfi is cleaner at idle, it was more of an emissions issue than performance. Remember the ' nickle theory': any savings you can generate will ge multiplied by a factir of how many you produce, like hundreds of thousands in a car makers world. 2 tbi injectors are cheaper than 8.
