speartech 99-07 benchtop tuning harness and pcm's
I have a speartech tuning harness that works great, an 08 ecm for 5.3 auto silverado stock no changes made. Also a 99-03 pcmcia for 5.3 auto silverado. Sold all my hptuners equipment so I don't need this stuff anymore. This all cost me over 200 selling for 100, email me at gmtuner85@yahoo.com, pm me, of call me at 951-385-6406.
