If your egt is accurate, your fuel rate isn't much if any over a stock NA pump.
I would verify timing, I like about 6 deg with a healthy fuel rate, and turn the pump up a flat at a time till egts look normal.....power will be much better.
Gear ratio will help, even just going to 285s kind of takes the edge off of the power in my truck.
I had the timing verified but it's right at 9 and I turned up the pump almost half a turn. Smokes now where before it never did. It tows much better than before but still not what I'd hope for. Of course my last truck was a new ram 2500 cummins and I was probably spoiled..... long story short my family exceeded the seating capacity and I got a minivan..... so this truck was supposed replace it for camping and off-roading purposes. But man it's not even half as strong as the ram.
There's a huge grade by my house I'm going to try again. Last time I hit it floored in 3rd maybe able to maintain 40 mph or 35. But over heated over the top.
Hoping the timing which was previously-3 was a big part of the overheating. I agree with previous post maybe looking for a boost leak but no idea how to test for that. I was under the impression 7-9 for a non waste gated ats kit was pretty normal so.....
I was thinking gears would be just right with 4.56 to tide me over till I can do a cummins swap and move up to 37's. I haven't ever driven another idi turbo truck so it's hard to know what to expect as if it's normal or under powered. ??
