To be fair, no custom tune is going to beat the latest BM3 OTS maps since they already max out the stock HPFP.
And now that the Stg 2+ maps are out, no custom tune is going to beat the 2+ OTS unless you have a very specific situation like a Stage 3 turbo or are tuning with meth.
But the custom tuners will gladly take your money saying they can do better, not offer any refunds when they don’t, and some of them may blow your motor trying and then blame it somehow on you.
