New guy with questions needs help

[Seanblv]

Hello, all. A few weeks ago I turbocharged my 2002 Silverado 2500hd. I paid to have it tuned, as I have no tuning experience. That?s the last time I do that. The truck runs pretty decent, but it definitely has a few hiccups in the tune. I have gotten a few check engine lights, once it went away after a day, and once I cleared it a day later. The codes are something like, o2 sensor heater circuit voltage high, and one for maf sensor circuit voltage. The maf and o2s were turned off in the tune. What could be causing this? Thanks in advance, I plan on buying hp tuners very shortly and learning a little bit of tuning, but for now I?m stuck reading.

For anyone here to really help you need to post your tune and logs (I know you can't do that right now).
Maybe someone could give some advise if you have the specific codes. MAF code is possibly for the signal being exceeded due to your turbo.

Thank you. As soon as I get hpt I will post the tune. I?m not trying to get into full-blown tuning, but I would like to figure out how to clean up my current tune a bit, and not pay someone else to do it again. As far as the maf, it?s not installed anymore, it is an sd tune, but the temp sensor wires from the maf are being used for my IAT sensor. I will also get the codes pulled again and find out what they actually are.
