I'm running a 93 street tune. It gives me no problems. I had a 2007 and ran a 93 race tune constantly. This street tune is no race tune. I'm reluctant to say that my 2007 with a 93 race tune felt faster than this 2011 with a 93 street tune. Same tuner. I know it's not.
Just got my 3rd race tune uploaded tonight and it runs perfect. The problem with the other tunes was the timing was too advanced for my pcm. My strategy is VXT3.
