Well, here's a back story. I tune local cars for a bit of extra spending money. So far ive done about 11 local cars and a couple that i tune that are not so local. Basically, they send me scans and i make adjustments.
I tuned a local guy with a 3.4 setup (3.4 pulley, ported blower and TB, Headers, etc.) When scanning the car i noticed that the O2 sensor was reading wrong. Instead of going back and fourth from low to high, it was hovering around 450 no matter what throttle position it was in. His rear O2 was also deleted. I told him multiple times not to do any wot pulls until he got it replaced. The next day, i see that he went 130+ on the highway. I called him out on it saying he will blow his **** up if he keeps doing it. Didn't listen and a couple weeks later, it blew up. i know, surprise surprise. He blames the tune and swaps in a new motor. Then asks if i have an o2 extension so he can replace the sensor. To my knowledge he never replaced the sensor and blew the car up again. Apparently its totally my fault and i'm the worst tuner ever. What he doesn't realize is, it doesn't matter who tuned it because it would have blown up regardless. At least i had several other guys i tuned for stick up for me. This pisses me off so bad because i told him to fix the issue and he didnt. Then he gets on facebook with his brother and just talks **** because they think they know it all. I dont ask a ton for tuning, just gas and a little money for my time. I do it as a favor for my local 3800 guys, so they can spend their money on other parts and enjoy the dying platform. I do realize that if i tune lots of cars, this kind of **** will happen but, his tune was rather safe. IE, stock timing tables, PE and other fueling was tuned a little rich to be safe, ETC. I've no problem posting the bin file so other tuners can go over it to see what changes i made.
End Rant.
