Maybe im confused, or reading that wrong, but your saying doing a fuel system the right way is 10K, but then below you have an example of one that is not done right way, but half upgrades and meth and still 10K. If i'm gonna spend 10k either way, i would rather not have to blend fuel constantly to make E60 and now also have another piggy back (meth) waiting to fail and eat my motor. I can't tell you how many motors i use to replace due to problems with a cars meth system. Thankfully most guys have ditched it in the Mustang world.
