Poor dump trucker

The last 6 are 003215. Thank you very much for the reply! Depending on the cost of the turbo and injectors, I would be open to upgrading them.

I have searched the site and internet for a while now and I give up! Lol trying to increase the hp on a e7 350 in my 02 cv713 granite dump truck I have. It does pretty ok but it is definitely falling behind. At the quarry it works at, it misses out on an average of 1 load a day compared to all the other trucks running out of the quarry. Not looking to make a hot rod just want it to be able to run respectably with the 425-475 hp trucks it runs with daily. a good friend of mine ran several Mack’s in this era of trucks, he said he’s pretty sure the e7 350 can be flashed to 460 without changing any hard parts. That would be great if possible. I also have jpro and Vmack but can only get jpro to connect to the truck. Have also been waiting on the dealer for 2 months to get it in to put a 460 file in it and am tired of waiting on them. any help would be greatly appreciated!
