do you have at least a #12 wire operating the HEI? What engine do you have and what brand HEI did you buy?Also a extra ground wire on the HEI attached to the module helps.
Probably about 200 bucks.You can buy it and do it yourself but you have to sand the floor to do it.That why i paid to have it done.Its a dirty job.I went to ole el cheapo Earl Scheib on Cave Creek Road.He was doing it for 175.
You should have a ECM on top of the glove box fastened to the heater box.You have to take off the glove box door and take out the box and you should see it.
We used sprayed in bedliner for truck beds.The rough texture acts like a cool deck on a pool.Before you couldn't touch it:twisted: now you can.Were in Glendale
