I got 1.16:1-1.3:1 on the back pressure @ WOT, a 150-250 degree drop in EGT's and an average MPG increase of 2 mpg across the board. I also made 485rwhp and 965rwtq. I do not have track times. This was with the stage 2 and a tune written for the stock turbo. I've seen too many of these empty threads with guys just throwing how they like the way it feels out there, so I've started working on putting a Stage 1 in the hands of a very distinguished diesel mechanic with all the resources to answer all the questions on the stage 1.
I appreciate your input, but that's for the stage 2 turbo. We're interested in the stage 1 for this thread.
It seemed like when you guys were looking for someone to test the stage 1 there was a lot of criteria, and a lot of trucks to choose from. F-250-owner was chosen specifically, I guess I was just expecting more reporting from his testing than what has been shown. There were a lot of trucks to choose from...
Why do you have to put one in the hands of someone else, a diesel mechanic buddy, isn't that what we were supposed to be getting here???
I understand there have been issues now, but he did have it on for over a month. No way of monitoring BP? No drag times? I mean real world use can be very helpful, but we haven't exactly got a lot from that either. Don't know the weight of the setup being towed (we can rough guess based on the size of his camper I guess), some EGT numbers I guess, but not even with updated tunes.
F-250-Owner, this isn't a knock on you. I know you're just doing what you planned to do all along, and you were chosen for a reason, I just hope we see some more data when you get it back!
opcorn:
As far as this being a "drop-in" turbo, I don't doubt that, but is no one planning on getting updated tunes anyways to get the full potential? Seems like we would be leaving a little on the table without doing so.
