RHoughton1 Posted November 4, 2011 Report Share Posted November 4, 2011 This is why i suggested a Blackbear tune. He sends you a terminal hook it up then mail it back and he custom tunes it to your specific vehicle.You might try the company you ordered from to see if they offer a custom tune specific to your truck. 'If it ain't broke, don't fix it,' unless you're a tweaker, and in that case you already fixed it ten times and it's still broken. - Dave Mustaine Link to comment Share on other sites More sharing options...

Thanks for the help. What/how exactly do I tell PCMforless this problem and what can they do? edit: Yes same sensors for 305 and 350, just different in wiring harness I believe as the 305 has 3 precat 1997 Chevrolet Silverado Extended Cab, 350 Vortec Things to come at some point...

RHoughton1 Posted November 4, 2011 Report Share Posted November 4, 2011 I would call tech support and let them know about the swap and see if they can recalibrate the o2 sensors to the correct air/fuel.

Thank you, sir. I have called them a few times and this last time they have told me to unplug my sensors and see how it runs after warmed up. Will be doing that tomorrow and calling them again until my money was worth it. I'll keep this updated just in case anyone needs this information...I didn't find much help searching the Internet for my problem.

Loslam Posted November 4, 2011 Author Report Share Posted November 4, 2011 Here's the results of unplugging the oxygen sensors and seeing how it does...lol. Wide open throttle, flat ground no hills or anything. Pretty damn disappointing. 1997 Chevrolet Silverado Extended Cab, 350 Vortec Things to come at some point...
