We have a truck here with a strange issue...customer has a 4.8 Chevy truck with a procharger....he sent his pcm to "Fast Chips" for a mail order tune ...he put the pcm back in and now the truck wont go over 16% throttle and the fuel trims are Wacked out....

Can any one take a look at the file and see if there is anything we overlooked?....we put a new file in it with the injector change and it does the same thing....Could the pcm be Bad?

Any Ideas?

Had a quick look over the tune and I seen there were a few out of range parameters here and there.

Personally I would consider the tune data to be corrupted and would not use it.

I think you would be better off starting from scratch. If I had tis to web I would download the latest OEM calibration for that vehicle and take it from there.

ED is a well respected tuner and I'm not into hanging shit on other people but something has gone wrong there.

JMHO if you want it done you know what to do.
