Custom Tunes

[blackwrx]

what sought of boost / air flow ratios should I be running?

I would rather be a little conservative, the rex was running 16psi really kicking in at about 3500 rpm and pulled all the way to 6000 rpm.

I dont think the fords with stock internals etc can handle that sought of boost!

but I would like to be able to spin the wheels if I wanted, when I test drove the car no matter how hard I pushed it the wheels did not spin.

Just be aware that too much boost too soon bends XR6T conrods....or at best drastically reduces engine life through component fatigue. So rather than insist on the way you want the engine tuned, pick a responsible tuner with all the right test gear and discuss the ramifications of your request. Its all good till something goes wrong, so make sure there is some safety margin in the program.
