A 62mm tbs and Valant cold air intake.
Before at 77mph for 490 miles was 16.5mpg.
Now w/ upgrade at 77 mph for 300 miles 20.1 mpg.
So final Vedic "IT WORKS PPL!!!"
Despite what the haters say. Works even better when u drive 65mph for 300miles. Averaged. 23.4 miles per gallon.
I run medium or high grade gasoline only.
I think work the money ion gas only. Will pay for its self in less that a 1000 miles of gas. Plus it sounds good.
