yup same hpt, buy credits and unlock just about any car these days, well any worth tuning at least.

so far i got the regal, the hoe, the work truck unlocked, got 2 credits left of the 8 it came with, not sure if the camaro is 2 or 4 credits, they tend to cost more for the newer cars.

i need to read up a lot more crap, seems this pcm is not gonna be much like anything im used to. might pay for some remote tuning. then maybe best to have it dyno tuned once boost is added.
Work truck too lol?

it needed evap codes deleted to pass inspection, ive tried to fix it many times, huge fail over and over, so delete....

and of course i changed a few small things in the pe settings to help it move better. its a 05 chevy 3500 mason dump, how much help is that gonna need while its loaded to the gills. you cant beat on it much so i figured stock it should stay.

Yea, I guess that is all. So, not really a big deal. You are only to use Pro-Charger oil and I change mine every 3000 miles. It's just a pain if you forget to order it when you use the last bottle. I've seen others have used different brands of oil but then you follow them along and they seem to have issues. It does have a special sound when it's running that is hard to conceal.
Here is a video of it just after I changed the oil. Using Royal Purple in the engine and the Pro-Charger oil in the unit. I have the Airlift jacked up to get it on the ramps and help get under it so it looks like a 4x4.

Interesting; my Whipple only needs the oil changed at 100,000 miles.

Stopped dragging my feet and got it all together. Did front wheel bearings on it too, will tell that story when I'm at a computer.

Just waiting for some buddies to get an opening in their schedule so I can get a hand torquing the harmonic balancer bolt. Why it's tty instead of a woodruff key and flat torque I don't know.

Should have bought the ARP one, it is just a torque once to 235 ft pounds and reusable as well.

Hindsight 2020.

Not really a big deal, I don't plan on taking this thing on and off much. I just can't gun the sucker down with an impact.
With the stock one, you're supposed to torque it to 240 ft/lbs, then remove it and throw it away... then take another new one and torque it to 37 ft/lbs and then attempt to turn it another 140 degrees...stupid IMO. The ARP one makes it easier. I used a pipe inserted through the holes in the harmonic balancer and wedged it so the engine couldn't turn over and then torqued it a bit past 220 which is all I could manage.

On my way home from work tonight, the 05 started spewing steam from under the hood. I was a few blocks from home luckily so I made it. The connector where the heater hose connects to the block had broke. That required a complete hose assembly that connects to the firewall, block and overflow tank. It was easy to replace though. I already had a new quick connect for the firewall so that came in handy.

How do you like those side mirrors? They look like the Ford style and they look good by the way. I'm thinking about going with them. Mine don't have the blinker lights in them but I can tap into the wires somewhere to make those work.
These are the 2015 style lights. They are manual mirrors. But they came with the wiring for the blinkers and the reverse light. They work great and the reverse light helps out a lot when backing up at night.
