You guys with 3.55s, My IDP tunes hit OD at 45 even just cruising around. What do the GH tunes do
im sure you could tell matt to make it whatever you wanted it to be.
i got his tunes on my 7.3, on the way for my 6.4. he will tweak however, whatever it takes to make it how you want it, so your happy with what you have.
we tweaked my heavy tow tune 3 times, moving the shifting around, getting it where i wanted it.
thats whats great about matts. if you dont like something about it, tell him. he will change it.
he is NOT, this is my tune, take it or leave it.
