just looking for opinions (opening a can of worms) on whether or not I can run my full synthetics 7k or dino at 5k with the slight mods listed below:
2001 Ford F150 with 5.4L, 92k miles
Hypertech Power Programmer increased 1-2 and 2-3 shifts by 300 RPMS and redline by 400 RPM's.
K&N Series 77
flowmaster cat back dual exit
looking at headers (only due to the fact that i have to drop the manifolds due to rusted studs and now a leak)
just wondering because I see on the Amsoil site that they don't provide the warranty/guarantee/recommendation for extended drains on vehicles with any mods.
TIA.
