Hey Ranger well I ran my buddy in his stock 03 cummins ram and tortured him all over the road in my superchipped 7.3. He put a few chips on his and outruns me now. I think your buddy is blowing smoke on a 340 hp chip. I've never heard of a chip alone providing that much horsepower. Even if it did he'd have to modify just about everything else in the drivetrain to actually make it effective. Talking a much larger turbo or a twin/staged turbo setup, injectors maybe, definitely tranny upgrade, lift pump ...FASS fuel system something.....there's a company called TST that markets a high powered box, it's like 190 horse and 580 lb ft of torque with some slight mods..
