MAF Sensor Problems

[RUFFNECK]

I have a TSP 220 cam in my 5.3. Dont have it tuned yet, the tune is not stock it is tuned for a LS1 cam. I finally got the headers on so waiting on that. But, for some reason I keep goin through MAF sensors like crazy. I know I need it tuned, which I really been trying to find someone to do this, but just wondering if vacum leaks would cause this problem. Right now it flashing the SES light all the time, but when I unplug the MAF it goes away. I just replaced the Intake gaskets and fixing to replace injector o-rings. Just wanted some opinions or some who have had this problem. Its throwing codes p0171 p0174 and running lean.

dude come on now, you put headers on which lean a motor our and requires a tune, you did a cam which needs tuned for but you havent.......Dude you need a tune plain and simple

Yeah DUDE thats what I gather but the tuner I have is too busy to get ahold of as is others. So I guess Im just gonna have to buy the dam software myself and do it.

now you got to hope and pray you didnt hurt the truck by not having it tuned right away.

It stays parked most the time, weekend warrior. Dont really wanna get a mail order tune, just want a good wideband tune.
