Well, I finally had time to play on the interstate today.......
Of course there was a gusty cross wind & I ran it back & forth to see what the times would be....turns out to be the same, but I think that I could have achieved better results without the gusty wind.
Turns out my 0-90 times dropped by a full 2 seconds. Didn't know what I would expect, but I was hoping for better. I will try again after the wind dies down another day & see whats what.
0-90 in a dismal 19 compared to 21.9......(& that time is for an EXT with 2 wheel drive only & NOT 4 wheel!) but like I said, it was very windy today & so I may be able to do better. ---probably could do better if I cleaned the thing out on the inside

Tons O' crap on the inside

Baby toys & work junk everywhere.
Plus that & the fact that I am relying on the TB's timer on the dash. Not the most accurate huh?!
