VW Mk4 Jetta, Golf, New Beetle, Passat TDI forum
What is a good size of injector nozzles to use on a 99MK4 ALH with a Malone 1.5 tune? Looking for a little more power and torque. Nothing crazy, trying to keep fuel mileage as good as possible. Engine is stock, still has the Vnt15 turbo, does have 2 1/2 inch straight pipe out the back.
