I must have not been clear!
NOT by changing any parts but buy tweaking the 87 tow program to get the most out of it?
Without overloading the engine!
Has anyone adjusted their settings that resulted in a substantial improvement?

I have 06 mark lt 5.4 with custom 87 performance tune and the gotts, the best I could do was 9.05s and 16.99 ( looking for a little better)
Is there a big weight difference between f150 4x4 screw and a mark lt?

Thanks

Theres not a whole lot you can do with the gas engines as far as getting substantial hp gains. Another thing, the 0-60mph and the 1/4 times are inaccurate, meaning they have a quite large level of uncertainty. Just keep that in mind when you run these tests.

Well I guess I might as well add my input

canned 93 perf. 0-60 was 7.1sec

custom 87 perf. 0-60 was 7.0sec

Cant quite remember what the 1/4 mile times were.

Best I'm getting for the 0-60 is 8.5 to 10 on all my runs. That is on every setting including 87 custom perf. I've got the 4.6 with gotts mod, but also alot of heavy metal like tools and a grille guard.
