I have been reading some people have been complaining about their early L99 cars not running as good as they should with 6 to 7 second 0 to 60 times (GM says 4.7 sec.). Later ones seem to be ok.
Some have read the later files and said there were several changes done to the tune to correct this.
Does anyone have a later tune file (around 30,000 & up vin) that they would share with me or post it up? I posted my early one, vin 3xxx, in another post. Inquiring minds just want to know.
