It will come with the whole kit and the PASS software.All included...It does have a few scratches on it but all in all it's top of the line.This can tell you what your touque and HP's Are along with you 1/4 mille time. For more info ... G-TECH/Pro Homepage ... this is the RR Retailed at 300.00. I will give this away for 250.00 OBO, or some S13 hatch parts.
