what should I expect from these mods??

steeda pullies, MM full length subframes, and a diablodalta chip. I have a local tuner, to install this stuff. We aren't going to dyno it yet, save the 200 -250 for later, when I actually need it. He is a diablo dealer, and has all of their software. I am looking at $555+ s/h. sound like a plan? I was going to get a control arm set, and the subframes, but I can't pass up the deal on the chip. I was going to also get a sct exc2, but I wouldn't know what to do with it, other than read codes, but with an autozone everywhere, the chip should be good for now. any feedback is welcomed. thanks, chris

I was thinking about getting the excal2, but for now, I really don't need that much adjustability. I guess it is a revolutions chip. haven't seen your name for a while! 4.6 modular. and I am getting the chip for 125 , vs 375-400 for the excal2+300 for the software. I can get free reburns, whenever, and trust the guy who works on my stuff. It was inticing to get the excal2 though. but pulleys, a chip, and subframes instaled, for 150 more? and some ss brakelines. just never got those put on. anybody have any realistic gains to expect??????
