Finally tested Gryphon!

Definitely have seen awesome low end gains. I was only unhappy with the shift points and firmness but changed them and now it is way better. I think it is all a matter of picking what works best for my needs, wants, and specific mods. I deeply appreciate Bills mind set concerning our trucks. Can't say enough about PHP! Cody has always been extra helpful too! And I am sure everyone else has an equal re in PHP's success. I have already trimmed the bumper skirt plastic but now I have new rims and they rub.17x8 +6 offset instead of 17x9 -12 offset. Big 'O claimed they would end up being the same but I disagree. Will it be much of a big deal if I go with 33's instead of 35's? Having 4.56 gears.....

I dont think it will be a big deal, but you might not like driving on the snow as much because of all the extra torque that will be put to the ground. that will also make your truck feel faster off the line, but it limits your top end, but I'm sure you already knew that

You'll have even more low end if you go down from 35" to 33".

As for performance gains, the CAI and custom tunes are not compounding. The gains you initially had are somewhat offset by the custom tunes because the slight lean condition is corrected for safety.
