It is now 40 days since you published your mod. You must have refilled your tank at least a few times since then.
So, what are your findings for fuel economy?
I am considering this mod if I can find a way to reverse it in case I'm not satisfied. If I do it, I will do a before-and-after side-by-side comparison with Salima's GTS to see if it is all just a placebo in our brain or reality on the tarmac.
Stay tuned, and let's hear your fuel consumption data.
