hi, i know someone that his brother bought a msp and he said his brother put the psi to 10 with a manual boost controller without any kind of tuning....i know its really bad but what kind of problem can happen?blown engine...probably. Even if he had a tune, would he need like a downpipe at least to put the psi at 10?
also, if you go to a tuning shop, can the guy there tune your car over the original map without any em...or you need to buy one? i now there is cobb accessport for the speed3 what is available for the msp? so the question is can you get a tune without any EM? What is the cheapest one?
