Hello,
I have a 2006 Silverado Z71 with a 5.3L and I was wondering what performance chip/programmer that I would get the best result from? Hope to hear back. Thanks
I was torn between the two; hoever, I gave a Wester's PCM a shot for grins and olyfugginchit, I was blown away at the 180 it made for my Tahoe. I did some minor things and she will now scream up to 110 with ease. Now, it isn't supercharger fast, but you will notice a HUGE difference the moment you step on the gas.
