But my truck doesn't even smoke the way it is lol. There's no un burnt fuel. I just have a hard time wrapping my head around this. If my truck is already burning all the fuel how does adding more air make it faster with no more fuel to burn? You can see I literally have no smoke in this video

The combustion process isn't "linear" so to speak. It gets very inefficient with more and more fuel and air. You can't really judge power based on which truck is burning cleaner, even when you know the mods of each particular truck. Your elevation definitely isn't helping any.

Yeah that's why I don't understand why my trucks not performing. I'm only 6800lbs, good low elevation. Stock turbo trucks are running faster than me at my weight

did you post a log of your run? Unless that "modded LLY charger" isn't doing anything for you, it seems like something is amiss.

I'm not sure how to post a log. The charger should be badass. It's a ported Lly charger with, tct wheel 10 blade turbine and fingers high flow vanes. It's a little bigger than my stock lmm but not much. It has the potential to move a lot of air.

I'm going to have Kory bump up my pw to 3200. Another guy on here has the same charger tuned by Kory and ran a 12.6 at 106 mph at 6800lbs. Only difference is he's at 3200pw vs my 3000.

I ran 13.07, 102.90 at 3000pw at 6800lbs. The other guy also has a lock up box. So with the trans tuning I ordered and a bump in pw to 3200 I think I should hit those same numbers. Kory is just trying to keep it safe and not have me come Bitchin if it blows lol. I just want to get a good time at 3200pw then I will re flash to a lower pw tune till I can get some bigger injectors.

if you're around 160mpa you might not be hitting full P/W in the tune. That 3k number might only be at 180mpa. FWIW a max effort tune at that pressure is usually between where you are now and 3250, so maybe a little more fuel will get you there, but I'm surprised with that turbo that you aren't already deep in the 12's.

Not that it'll make you feel better, but my buddy's 2wd crew cab LMM weighed a little more than yours at the track. He was loaded right from work with his tools and even had a case of windshield washer fluid in the back seat. His truck had a stock turbo and fuel and on a max effort tune with water/meth (winter WW fluid) and a built trans with an ML converter and went 12.6 at Atco, NJ once he dead hooked h2 wheels with 285 hankooks.

I'm not sure what my mpa is. I will have to go look at my log and see. I have seen several stock turbo trucks run 12s all day long at 6800lbs. I figured I would be deep in the 12s with this turbo also like you said. That's why I'm not sure what's going on.
