I got my car back from being tuned about a month ago and it ran great for one night then out of no where im driving and the car acts real funny and shuts off. i hear a fast clicking sound from the fuel pump relays and my fuel pumps are in sync with the sound. (i have a 255 in tank a votech t rex and a kenny bell boosta pump) If i pull the chip out and turn the key on the clicking stops, put the chip back in and the car will run for a short time? I can let the car run in the driveway for an hour but as soon as i take it out and put a load on it the car dies. I thought it was a bad ground so i regrounded everything then i put a new computer in it and last i put a new computer relay in it.WTF Im thinking its got to be the chip right????
