Unless you really seriously change the cam and other things, it probaby is unnecessary.

You'd be amazed at how adaptive the stock EEC system is.

For example I ran an F cam, TFS aluminum heads, TFS intake, and full length headers and the stock 19lb injectors were fine with just a slight increase in fuel pressure. It was good for high 12's at 108 MPH with no tune at all, and A/F ratio was near perfect.

I finally had to tune the car after installing a blower and larger injectors on top of all that. It was over the 110 MPH range (350 HP) where I had to change injector and MAF parts, and change the EEC.

Save your money.

With a stock engine or mild mods like those listed, you wouldn't get enough improvement to justify the cost. What they do is put it on the dyno (usually $65 an hour), and typically it takes 3-5 runs to narrow it down while they tune it. Once they get it right, they take the data and burn a chip (usually $250- $300). It'd wind up being around $400 for it to be tuned.
