[QUOTE="Blowby, post: 271223, member: 711"] It was with the blue truck (F350 / ASB) and I tow'd a lot. I put about 80K miles in two years towing, DD and racing with the Hypermax B-codes with .010 edm nozzles and internal modification. I had them gone through not long before I pulled the motor for the F250 and had a little work for a smidge more fuel. I then ran at the Bakersfield NADM event with the motor in my F250 and it calculated 637hp on ET. [/QUOTE]
