Tune Help
UPDATE: Added a gallon of coolant...guess I should've checked that first but after spending 8 months at the builder I assumed all fluids were topped off. Also shifting still doesn't seem quite right but I'm sure one of the experts will be able to look at this tune and tell me why. I added a log but couldn't really get on it as my passenger was a little scared so no real WOT stretches on the short drive. Thank you again.
Can someone look at this tune or make a recommendation on who is best to provide recommendations? my 03 has forged bottom end, mild BTR SC cam, long tube headers, built transmission, A&A SC w/3.6 pulley, 80lb injectors, and A&A fuel system. Initially I got the P1870 code because i swapped in 3.42, and now that's cleared up but I just don't trust the tune...maybe I'm being paranoid but if you've followed any of my posts on the Corvette forum this build has been an 8 month nightmare.
Test drove this newest tune yesterday in 85 degree weather, overheated twice in traffic, then wouldn't go below 240 degrees the rest of the way home (20 min). I also noticed the oil pressure seemed to be low but maybe not...only about 30 psi while cruising at 60 and not getting any higher when I accelerate. It was down to about 20psi when idling. Any help would be greatly appreciated. Thank youAttached Files

I'm looking.
This is a MAF only tune.
You aren't logging near enough stuff.
Is there a wideband?
I don't see coolant above about 196 in that log. And oil pressure isn't present.
Try logging it with the channel config below.
Save it to C:\Documents\HP Tuners\VCM Scanner\Channel Configs
Then choose it from the scanner.
Hopefully you can figure that out, it can be confusing.

Updated Tune again...hoping someone can jump on and provide feedback. Car still won't start on first crank after sitting for a while but starts immediately after it's been driven. I've also started to be overwhelmed by gas fumes and after driving today it smells like its actually coming from driver rear tire. Thanks in advance for any feedback.
