From the research I have been doing it’s a toss up on ease of making tdi mechanical injection vs playing with wire harness. For me, to many pros for keeping the wiring harness, from reading alot about this swap, with tuning / programming (Malone) you can have a power house from this little engine and still get good? Mpg. Supposively more power and more mpg from tuning so I will be cutting wires and mapping it out. Either way, both have to be better then the 22r / re / and 3.0.
And the truck the tdi is going in has sas with lift springs, hopefully all will fit nicely, or we go higher!
