I ordered a superchip for my 99 SVT. When I gave my calibration code he said that "most likly you will have to modfie your computer". He said to wait till I get the chip and then plug it in to see if the car starts. If the car dosent start I will need to solder 2 jumpers in my ecu. So I waited and got the chip and no surprise my car didnt start. I e-mailed superchips to get the diagram. When I opened up my computer it didnt look any thing like the diagram they sent me. So i'm a little po'ed.

And I'm waiting for superchips to get back to me. But I wanted to know if any one else has had this problem and how it went for you.
