I commute with this van and 8-10 passengers over 250 miles a week about 75% highway at 60. This was the primary reason I got this in the first place and although I was a little unsure at first I am now a believer. Cruising at 60 it will shoot right up to 75-80 in nothing flat.įuel Economy – Also good improvements. I haven't really used the tow setting much yet on the road so I can't say how it handles with a heavy load - only that it left my poor sister in a cloud of flying gravel and black smoke the first time I tried putting my foot into it : ) The econo setting has better acceleration all around, especially kicking it up to pass at cruising speeds without having to downshift. Power – Drastic improvement! Went from 16-17 sec 0-60 (Yea, I know It had a lot of lag time waiting for the turbo to wind up.) down to 10-11 sec in the tow setting and 14-15 in the econo. Been using it for 5 months/nearly 10k miles now so here is my review. A 1300 RPM high idle, 60 Hp Econo, and 60 Hp Towing, as well as Stock. Got and installed an F5 16 Position Chip from DP Tuner in early June 2012. No idea.I have a '99 E350 12 passenger van with 7.3 powerstroke. Might take a look at it tomorrow and see if it was possible he might have bumped the chip and it moved on the PCM or what. Kinda interesting though it happend on the same day, with a new DP tune installed. I guess he pulled over to the side of the road, and pulled the chip out, and restarted the truck. Every light that could pretty much come on came on, and the truck lost all power. He said if you looked at his gauge cluster. But called this morning wondering what was going on. Just made sure the key was out of the ignition. You are supposed to just take the silicone off, if you go to the copper youve acually gone to far. The PCM was already cleaned of the silicone. His truck already had a chip from the previous owner. He sent it out, got the same tunes i had burnt for his 2000. I recently got rid of my perfectly fine DP.
