After thinking about it in my previous thread, I may add a smarty and use my TST for the gauges and to add rail psi or duration on the fly if needed. My main goal is to have a "daily driving tune" that gives low smoke, decent power, and reduced timing rattle in the 2000-2500 RPM range. The main thing I'm looking for is differences between Smarty Jr and Sr when it comes to lower power level tuning and compensating for my larger injectors. I'm leaning towards the Jr, but only want to buy it once.
