I have a 2005 Jetta GLI MK4 with a ecu upgrade already. I have a blow off valve and the exhaust flows pretty freely. I just bought a front mount intercooler that I am going to install with 3 inch piping. It runs 15 psi right now even 20psi in first gear if I really push. I dont want my pressure to drop with this fmic. Would it hurt to put in a boost controller? Or beside that fact can you get a bit more boost with one on top of the ecu upgrade? Somebody already did alot of this work and I'm adding to it.
Boost Controller Jetta Mk4?
