What engine you tuning?

I drove the Ranger to work yesterday because the F-150 was at the shop getting an exhaust system put on (Flowmaster 40 series SI/DO), and I felt like the Ranger was working really hard to drive 60-65 mph, feels a lot different lol.

Yeah I drove mine the other day and it felt sooo slow, and with it being a stick was funny to drive again. I think the top speed on my Ranger was 80 downhill haha

Just 2 more days and I can finally place my order for the Gryphon. Seriously can't wait.

Best 0-60 as of right now is 9.12 on Gryphon stock level 2 but I can't find a place to do it without getting major wheel spin which makes my foot let up a bit without me thinking.

Once I get as much of this 87 octane out I'll be filling it up with 94 and setting it to level 3... then I might have to buy some new tires...

Oh and the belt chirp is awesome at wot when shifting. I have never owned a vehicle that was as fast as this thing is now. I forgot I had a V8 under the hood. I used to have a 1976 Chev C20 with a 350 and my little 281 Windsor out does it hands down now.

I checked mine, I am getting 7.63 for my 0-60. Im running a custom level 2 and have 33" Load range E. Does anyone know how to convert your tire size to the (mm) on the gryphon? When I do my conversion of 33" to mm I get 838.2mm. Something that I am missing?

Sure - the 838.2 is your tire's diameter in millimeters. You need the circumference, so multiply that by pi, which gives you 2633.3 mm. But then, deduct some for "squish" (often about 3%) so multiply by 0.97 and you'll have 2554 mm, which is the size I'd try.

If at all possible, use the manufacturers website to determine the "Rev per Mile" rating of the tire. Then to convert to millimeters, use this formula...

1609344 / Rev per Mile = Tire Circumference in mm

That helps eliminate any guesswork.
