I cant say enough about the service from cal and holly.....we finally got the car ready to fire for the first time ever at 7pm tonight,took a shot in the dark calling them at that time of night,they both were able to help with the start up setup in the xfi that i purchased from them a while ago,we lit the car off and cal walked us through everything,(and he was at a race doing this for me over the phone)...i am so glad that i purchased my xfi from them,they are top notch and the technical support is priceless!!!!
