New to HP Tuners - Running Rich & Very Sluggish/Hesitant takeoff

[1972C10_LS]

Swapped a Gen IV 5.3/4L65E into a 72 C10 2wd pickup. Had harness done and ECM/TCM modules flashed with what they called a 'performance' tune. Im assuming this was a blanket tune that 'worked' for these engines and transmissions. Now, it starts, idles and drives ok. But it does not have near the snap and it smells very gassy. Im hoping someone can point me in the right direction on what would cause these behaviors. I've attached a short scan/log and the current tune. The only thing I've done is taken out 75% of the torque management but it doesn't feel that much different, still wont do a burnout from a stand still!? Also, this is a completely stock engine from a new body 2007 Silverado. Only modifications is a CAI and headers.

Thanks in advance!

Add AFR commanded to your log

Also add commanded EQ ratio

It's going quite rich in a lot of places on the log--the question is why.

Fuel trims bank to bank are like 10-15% different.. that is usually indicative of a vacuum leak or very bad injectors. Are you using stock injectors?

[1972C10_LS]

Hmmmm...Yes I am running stock injectors. The engine sat for a few months but it starts right up and idles fine so I didn't even think about injectors.. The only DTC is a P0449 Evap Emission System Vent Valve/Solenoid Circuit but I think that is because the modified harness doesn't have that connector any longer.

Hmmm. Is the evap system connected still?

[1972C10_LS]

No it isnt. The only vacuum related thing that is hooked up is the brake booster to the large nipple on the rear of the intake. There is a solenoid hanging on the drivers side fuel rail that is just hanging out with nothing plugged into it. In assuming that is part of the old Evap system?

I guess it is connected via hard plastic line to intake manifold but electrical connector is not.

We removed it and plugged the nipple on the manifold.

Im unsure how to add the AFR Commanded and Commanded EQ ratio to my vcm scanner logged items.

new as well and having similar issues on bank 2. Thinking bad 02 sensor.
how do I post for help on here?

[schpenxel]

Yeah that's the evap solenoid. Zero out the LTFT purge reduction table just to be sure it isn't doing anything. It's under fuel-->open/closed loop.

To add PID's, go to table view, right click on a blank spot, insert and then find those two. Double click on then and it'll add them

[1972C10_LS]

Ok. I will do that and go for a drive to gather some more data! Its weird that in the DTC section the box isnt checked for the P0449 to activate the SES light but yet it still logs the code and activates the light? Anyways, thanks for your help! I will post the log again when I get a chance.
