Interesting reading from all Recently put my car on the dyne for a tune as it has had all the usual mods fitted, cooler, full exhaust, pump, injectors. The tuners have told me it is over boosting and I need to replace the waste gate as it's spiking to mid twenty's in boost and keeps popping the air intake off the throttle body, I am no expert when it comes to forced induction but any help would be great help. Cheers
