So Im going to buy a 2010 F150 STX 4x4 w/ 4.6L 2V.Im going to lift it 6", put on 37" toyos and 4.10 gears. I want to get custom tunes either on an XCAL3 or Gryphon CS.. I want it to get a "highway" tune and "city" tune as my driving characteristics change between the two. I want these custom tunes to be set just for MY engine, MY intake volume, MY exhaust output, MY tire size and MY gear size. I basically want to have a "super tune". Like a max power, tow and fuel economy tune put all into one tune that is ultimate. My question is: Do I have to get on a dyno or can the folks at PHP just send me the two tunes already preprogrammed into it? I guess what Im trying to get to is... Do I have to drive all the way to Georgia to make my truck absolutely PERFECT for MY driving?

 

Time talk to a tuner.....
Use the links in my Sig to contact them.

 

37's with 4.10 gears???


don't even waste your time and money


go with 4.88's or leave the stock wheels on there

 

37's and 4.10's will have plenty of power. Its the perfect combo for highway mileage and around town mileage. I have 4.56 with my 35's right now and thats just way too low. I should have done a 3.73 or 3.92 with them. But I was dumb and read those gear ratio/tire size charts.

 

Wrong! Your going to feel like you're stuck in the mud dude.

4:88's will be the closest to stock with 37's.....you can argue with TJ but he's correct.
