Phoenix Switch-On-The-Fly Chip (DISCOUNTINUED) (Disabled)
Power Hungry no longer sells the Phoenix/TS chip, but if you need custom tuning we can recommend a few really good tuners that will be able to still provide tuning and support for your chip.

If you have any other questions or comments about the Phoenix/TS chip, please post it here.

Default Put it to the test

I have not had any issues and have been very happy with my Phoenix. We just returned from Glacier National Park, a 2400 mile round trip pulling a 10k 5th wheel between 65-70 mph the entire way with the A/C on. I pulled 12.77mpg round trip with the chip set at 65T. I was very happy with that. I did end up with two issues if anyone has any ideas.

1st issue- while pulling hard up hill prior to kicking down, the truck sounds like maybe the wastegate is maybe starting to move and sticking? Almost feels like maybe some turbo surge. Once the truck kicks down, it sounds and runs fine. When this would happen, the emissions light would come on for a while. Truck would run fine after this. Checked for codes when I returned home. None listed.

2nd issue- Went to fill the tank when I returned home. Set the chip at 80DD. Left the station and put it to the floor. The truck started off like a rocket, spit out 5 times the smoke it did any other time. Then it fell on its face of about a 1 second and took off again. It acted like someone turned the fuel off for a second.

Parked it at home and found a puddle of oil under it today. Took it to the shop, pulled everything off the top except the turbo and can not see any leak. Sprayed it down with brake cleaner to start out clean and will put it back together tomorrow and check for a leak.

Any help or advice would be great. Thank you

You really need to find out what the code was.....I'm going to go out on a limb and say it's due to a weak high pressure oil pump but don't quote me on that.



You probably were hearing turbo compressor surge, as hearing the wastegate actuation isn't possible.

The oil leaks that these trucks get are almost always attributed to something on the top end of the engine, but since you didn't see any oil in the valley, it's anyone's guess where it's coming from.

Thanks for the input. I had about 5-6 restarts on the truck and the code was gone. Guess I should have had the scanner with me. It is the original HPOP and has 180k on it. I'll set the chip lower and see what it does when I put it to the floor.

Pulled our 5th wheel up a 25% grade last year and developed an oil leak like you describe. Turned out to be the bearing housing of the turbo. Check it carefully. I kept thinking it was the pedestal leaking and removed and installed the turbo 3 times before I figured it out (with some help from a friend). It eventually started blowing oil in the intake and caused extremely hard starting.

I know it has been a while, but I thought I would give an update as to the truck. Turns out the oil leak was the fitting off the HPOP for the drivers supply line.
I did get to put my computer on the truck and it did not store any codes for the emission light. I will have a big pull again over labor day and will take my computer with to check codes if the light comes on again.
Still trying to figure out what is going on with the truck. The truck doesn't seem to have the same get up and go as it did before. I also don't recall it having that much black smoke when you get on it. When I put the chip back in stock mode, the truck runs like it did prior to the chip.
A work in progress I guess.

From the way your describing its an air issue. Check all your boots for leaks and you could have "hurt" the turbo a little.

I looked at the boots, and all are tight. As far as I can see, they are in good shape yet. Don't know how else to check them. Also, how would I check my turbo to make sure it is still fine? All of my turbo sounds are there, and seem fine.
