Here is what our customers think of GWN diesel, it is a shame we can not help him out.

"It's been 2 years running your tune and it's been great. However, I recently changed my truck to an "off-road" vehicle and have made changes to the exhaust system. I know you don't advertise anything on your website, but would you be able to offer your same tune but for a deleted system?

After deleting, I have been running tunes from Great White North Diesel and have SERIOUSLY been missing your tune.

If there's any chance you could provide one, with the same characteristics, let me know how much it would be."
 
I recently deleted my truck and am very eased with the results. I went with Great White North diesel for the time and exhaust. I ordered a flopro stainless exhaust from them (not on their website I had to call to order) and their 5 tune pack with transmission tuning. That package was cheaper than the place you found and you get more from GWN. So far in town I have seen 3-4 mpg better and on a 500 mile trip before and after delete with the same exact route I got 2.8 mpg better. I tow a nitro z20 bass boat and have seen an increase of 2 mpg towing so far. I am very pleased with the tune so far and with the EFI live tuner it is very easy to switch tunes.
I know this is super old. But just got my truck and wondering if you installed the flopro yourself. Looking at getting the same one here in bc
