Drove the truck around about 20 miles today and the shifting is way better, power is smooth and shifting isnt too hard. Compared to my 08 with Spartan 275 the power is way more smooth, the shifting isnt as hard, and there is no surge. I dont have the Hot Damn Downloaded but i cant tell right now if it is stout as the Spartan or not because it isnt near as touchy and violent but the speedometer moves da*n fast! I had the 120, 150, 210, and 275 on Spartan and so far i can definently tell you that the Black Maxx is stronger than the 210 on the Mild tune, my 08' was a turd unless it was on the 275 so that is where it stayed.
So i am about to start testing for fuel mileage, i have hand calculated 3 tanks so far with truck stock, first tank was like 11.5 mpg with mostly town, the next tank was around 150 miles highway with cruise set at 70 and about 5 miles town and it got 17.53, the last tank was a pretty good mix between town and highway and i got 13.72. I just filled up for the 1st time since deleting cat and dpf, so stay tuned for results.
Also when i first bought my 08' truck it had an SCT with DPF Delete, i think it had a 60 setting an a 90 hp setting, im pretty sure my 2010 stock would outrun my 08' with SCT on the 90 hp setting. For some reason that truck was just a turd until i got the 275.
This is in no way a bashing contest for any tuners, this is just my view of my black maxx, please no negativity. Also i am just going off memory of my Spartan on my 08' truck, i dont plan on installing a spartan on this truck either so it isnt a 100 % comparison. The Spartan could possibly act totally differnt on this truck.
I can also tell you what i LOVE about the Black Maxx. I trade alot and so it will fit any truck i trade for! I spent a small fortune on the Spartan and had to let it go with the truck because people were still unsure about buying a used one and you dang near had to give them away, this was when they first came out, i hear you can swap them from truck to truck pretty easily now.
