TST Box reflash

[Intense Marine]

How many people have sent there "TST Box" back to be reflashed?



What do you think of the "Box" now?



Do you feel a difference in power?



Do you see a difference in fuel milage?





I was very surprised with the poor fuel mileage I was getting once I put the TST box on my truck. About 4 weeks ago I stacked an Edge EZ with my TST box and my fuel mileage is better than ever.



Thanks, Brad

Do you mean reflashed with the newest program? I understand they have toned the program down a little from what it was doing last spring. I had mine flashed in June (it was a very early box) to get rid of the codes and see very little diffrence in mileage. You may have had a poor connection at the MAP sensor that was righted when you unplugged it to add the EZ.

Mine was reflshed also. Completly different box. 5/5 was 3/3 before.

I have my reflash back in. It feels like it has less power, but I don't think so. With the old program the trans would hold at 4/4 and slip at 5/5. The reflash does the same thing.

Don-T,

I have recently added the TST to my truck. Great product... I am assumin I have the newer flash. Power seems to come on very smooth but strong. I have heard others state the older flashh was very abrupt with how the power came on. I see that you have the FASS. Did you add this before or after the TST? If after what did you see for improvement? On a Dyno I could not get my torque to improve over 3/3 and was wondering if it could be not enough fuel? I do not have a pressure guage. . Yet. . I will at some point. I am curious to see if the FASS would be something I should do? I am not sure if the turbo is the bottleneck that should be increased before bothering with other components. This is my first diesel and I am starting to see how quick you can spend money on go fast parts.



Thanks, Jeff

The old program came on very strong. It would start to break the rear tires loose when the turbo spooled up. The new program does not do that. I installed the TST before the FASS. I was able to use more fuel than the stock lift pump could supply at anything above 3/3. The FASS fixed that problem. I have no idea wheather or not the FASS would show a gain in power or mileage. I do not have a fuel press guage in my truck so I don't know what the pressure is. In my case there was no doubt when I ran out of fuel.
