I have issues... i think. Today my truck was running alright with the adrenaline and was making lots of smoke, then i came home and decided i wanted to give the dyno tune a try to see how much it smoked. Well i loaded the tune and went out and drove around, and it smoked about as much as stock, and didn't add much power over stock. So i was thinking i did something wrong. So i came back home and loaded the 3000 tune, the tune i HAD been running before i loaded the dyno tune, and the same results on the smoke, but made WAAYYY more power than it did before. So i was thinking maybe quad updated their tunes to be not so smokey. So i loaded a tune, ADR2000 i think.., that i had run a while ago (I still had it saved on my computer) that was pretty smokey and i just got back in from doing a test run with it and didn't smoke much more than stock either.

I know some people will be like "why do you want smoke?" and "smoke is stupid" and stuff like that, but i'm 16 and you know the way 16 yr. olds are ;).

Anyways, i'd just like to have my smoke back, and was wondering if any of you knew how :).

Thanks in advance.

Here's my post from the adrenaline thread. Well I drove the truck all day today and still no smoke... so i figured "if i don't get smoke then i might as well have power" so i loaded the 3000 tune again. Well i was getting ready to go for test drive with it when i saw that the SES light was on. So i pulled back in the drive way. I turned the key on and off 3 times then a couple words poped up where the odometer is. The words said either "P PCU" or "P PCM" i'm pretty sure it said "P PCU", but i'm not sure... Anyways, i was just wanting to see what the P PCU means. If it could be a problem caused by the ADR or what.

Thanks guys.
 
Some numbers should have come up after that. Try it again and wait for numbers to come up and post them here. If it just says P DONE after that, there are no codes. If the light is on, something should come up.
