LOL, sorry i typed that wrong, not a t-5 cooler, but an oil cooler, mine came with 3.08 grs too, the 3.27's or 3.55's i heard can actually improve gas mileage because your motor stays in the powerband more often, anyhow the 3.27's i have improved a bit, and only run 100-200 more rpms on the highway over 308's,
but yea, i feel my car should ride smooth on the interstate, after all it was a THP.
Later...
