Have to confess we trailered it up. An experienced tuner took my Holley Sniper tune from good to awesome. In the tuning session we picked up nearly 100 whp and mileage went from 9 to 15 mpg. Greatest thing to me was engine temp control which I strongly believe was a result of the computer controlled timing. Two days of steady cruising through high 80-mid 90 heat in the middle of the afternoon. Made the circuit around the fairground at least 5-6 times. Never got over 195, nor out of 2nd gear. I agree it is the consistency as well. Quite a change in altitude from DFW to Mn-St Paul. The car was beautiful through it all.
