Injectors have approximately 200 miles on them, so does the Pro M MAF calibrated to the 42's. Used this setup with a Paxton Novi 1000 supercharger for sale in another post. Looking for offers on the matched set of injectors and maf, but will consider seperating. The maf was around 300 and the injectors 250, Looking for around 250 for the set,plus shipping. We can accept Paypal,Pickups are ok for locals.
