Anyone with the new flash please post your hand-calculated mileage comparison.

I'm a little skeptical if the flash actually improves the mileage or simply fixes the overhead calc. My overhead calc is usually 1 MPG less than hand-calculations. Amazing how that matches the TSB's claim of increasing the MPG by 1 AND fixing the overhead computer. Coincidence? I dunno, that's why it would be interesting to hear the hand calculation results from the folks who've had the flash. Thanks.

 

Just had mine done today and topped the fuel to the neck. Driving 300 + miles this weekend and will post actual MPG when I get back. It will be about 90% hwy and with the cruse set at 75-80 mph.

I'll let ya know.
