Nothing at all wrong with that combo. Or you could go with a TST or Edge box for all out power. With the Smarty you get the added benefits of code reader and eraser, plus you can recalibrate the speedo for different tire size.
That would be a nice combo smarty is supposed to really help with spool up and the injectors or nozzles will too. You'll want gauges for sure though. There are some other mods you can get that will give you more fuel up top than a smarty will so it really depends on what you are looking for, but with a stock auto, you really don't want a box that taps your pump wire anyways, unless you plan on buying a new tranny in the future anyways.
