Do I need anything else...........

I just bought the complete bolt-on kit from Vortech, do I need anything else? Should I get the car professionally tuned afterwards? Any help would be greatly appreciated. The car is pretty much stock. I have a Hypertech Power Module right now, will I have to remove this? I also have underdrive pulleys. Will I need sub-frame connectors? The car is a 94GT.
Thanks again.

They r plug & play unless u have visions of a lot more HP than is stated by the manuf.However, the underdrives w/have 2 go unless u want to figure out your belt size..Subframes will help stiffen up the chassis, but not absolute necessary..Am not familar w/the power module, but if it effects timing(which it probably does) it w/have 2 b removed IMHO...

Thanks midnight, for the time being the HP gain stated by the manufacturer will be enough for this year.

Please Some one has to help me out I want a princess peach bd& a plush I will trade anything. Offer me one and I will tell you what I have Thanks
