Why is my question? Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector. Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me. -

When a condition becomes a business model. https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/ Zane posted this in "Latest Articles". The honest bottom line Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management. Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage. Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land. -

Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks. Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's. This is our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on. -
