So since I installed my boost gauge I can now see the tune I have is a bit..... mellow. Only see 10psi max and hovers around 9-9.3 at WOT around 4500RPM in 3rd. I have read that GIAC tends to run the cars lean and I can see APR isn't what they used to be. So whats the best tune to get now since every year it seems to change?
