People building cars should watch this.

I did a few aftermarket fuel injection ECUs on some of my kids cars. We monitored air fuel ratio and we won't run the car if the ratio is too far off. Pretty standard thing when you run aftermarket fuel injection you should be monitoring AFRs and correct the system if its too rich or too lean. Sounds like he just slapped the fuel injection on the car and ran it without monitoring checking if it was working correctly?

Power Master alternator, yep I had one once. It was exactly like he said. Discharged battery at low RPMs completely useless part. I returned mine got money back went with some basic replacement alternator which worked fine.

Brand new Wildwood brakes that don't work, thats terrible, money down the drain.
