I recently had a new turbo put on my truck that was slightly bigger than the old one. I guess they changed the size to a slightly bigger one that they recommend now. Its a 63/67 vgt i believe and the old one was a 60/60. Truck ran great by itself, but towing a trailer it just felt like I was pulling a wall. Ended up being all the tires were way low on pressure. Like 20psi low in all 4 tires lol. They didn't really look low. My truck runs load range e tires which dont really lose air unless their is a leak. I guess either the shop adjusted the pressure or it lose a bunch of air while it was parked for a month waiting to get fixed. Probably the latter. The egts are right back up to where they were before. They dont go much past 900-1000. With the low tire pressure it was easily flirting flirting with 1200 even with light acceleration. All this time I was blaming the turbo
