Okay thanks for all the help truckin151.

 

got another question guys, Well i maid shore i was allmost completely emty and filled up with 93, Then switch the programmer from 87 performance tune to 93 performance tune and i must say not the gains i was hoping for. It felt like i loss power? it didnt have the tork like it did before and the pulling power at wot. I mean i only switched it to the 93 tune for an our and drove it but still. The only increase i felt is wot after 90 mph and thats it. the 87 perfomance tune witch i switched it back to now deffinitly alot better than the 93tune. What do you guys think?

 

For you guys that has have experience with the tuner, what do you think?

 

Okay... It is basically the same as the the superchips programmer in this aspect. The lower tune like the 87, pulls hard down low which makes it a great in town/city tune as well as a good MPG. From my experience, the superchips flashpaq was the same way. Now the other tunes are for more top end performance, and pull the best up top. Personally I am running the 91 tune and am more than happy with the results cause you can feel it more in the mid-high end, I guess (again just a guess) that the 93 is strictly a top end tune if that makes any sense.

One thing I will mention though is that you have to run the tune for longer than an hour, it needs time to "learn" the tune, really need to just burn a tank. Also the best thing to do before or after you load a tune is to reset the pcm, you can do the fuse trick or pull the battery cable and turn on your headlights for 10-15min or so and reconnect everything. Once you do that the truck has to relearn your driving habbits/style as well as the tune.

If it was me, I would set it back to the 93tune, reset the computer, and burn a full tank on that tune and then go drive it. If that tune doesn't feel quite right after a tank drop the tune down to the 91 tune (switch the tune BEFORE you switch the gas) and see how you like that.

 

Okay thanks truckin151 ill try that.
