ive got a 98 Camaro z28 that is all bone stock aside from a gmmg catback , and a slp complete cold air kit. I have a fast dual wb02 setup to monitor afr on both sides of the motor . Aside from the most obvious , no more 116'mph speed limiter , how much do I stand to gain over the stock tune and how much of a gain is possible with 104 unleaded ? Also does anyone know a trusted source to remote tune my car so I don't have to send out the pcm? I have hptuners but I'm green when it comes to tuning . This is only temporary as I plan on running a big cube lsx , with twin 76-78mm turbos by next spring . Looking to make north of 1200 to the tires for tx2k and ls fest next year . Thanks in advance for the help guys
