I understand that but, he has stopped returning my messages and I've tried to get his input on what can be done. Looks as if I'm going to probably out another $350 on top of the $365 I've already gave him so I can get tuning software to tune my truck myself.

 

Yes I do and both O² sensors are indeed hooked up. My snap on scanner is showing 13" of vacuum. I will see what the manual gauge says.

 

That would be the cam,talking.

Is this the one you have.


HiPoTek 210XP Performance Hydraulic Roller Camshaft Dodge 5.2/5.9 (318/360) Magnum

210/220 .512/.512 110 1200/1400-5200/5400 Modified PCM. Strong low to mid-range power. This profile on a 110 LSA is the same grind as the popular KRC 210X. 3.92 gears or higher. 2400-2800 stall works well. Works with stock head using performance springs. 8.5:1-9.5:1 compression. Street/Mild Strip. Mild 408 street cam on a 108 LSA. Fair to noticeable idle.

 

Yep, that's the one. I did however block off the factory MAP sensor port and turned the 90° elbow the opposite way and ran a vacuum line from it down to one of the lower vacuum ports so the MAP sensor would get a better reading. I talked to Richard and he told me how to set my IAC steps the right way and so far it's working. The tiny stock butterfly plates are cracked open pretty far but she's not stalling out. He said to ignore what the snap on scanner says as far as iac steps say because not all trucks run the 30-60 steps with this cam. Especially when I have a tiny throttle body that can't get the air in that my engine wants. So as of now I got his hipotek 52mm TB coming in, a high volume oil pump, pickup tube, Hughes hardened 1 piece 7.1" pushrods, Holley 24lb injectors and 1.6 roller rockers coming in soon.

 

Should be able to read the values on the upstream O2 with that snap on.......see what it says.

 

Now that I got it running without dying it jumps back and forth from rich to lean
and sometimes says center. Before I opened the plates up like Richard said it was just showing rich.

 

Does it run any better with the O2 sensor disconnected??

 

Now would be a good time to get that wideband 02 gauge and sensor. Narrow band will not give you much more info than what you are seeing.

 

Yeah I'm getting one on payday. Just gotta get it welded in once I do.

 

This is the one I will be going with soon, very nice piece but pricey.

And if you are not into welding a 02 bung into the pipe go with one of these, I used one until I redid my exhaust about a week ago.
