I have this chip..... F250 & F350 99.5-01 Auto 6 Position 4-Bank Chip ....... in my truck and it is working fine so far. But I`v heard that it is a bad chip and I should stay away from it because it is ruining the tranny in the end of the day.
What do you think ....... should I swap in something else.

Thanks

 

Do you have guages.

 

Yes...... boost, tranny-temp and EGT.
I also have shiftkit and new HD converter (don`t remember what brand, but it`s blue)

 

Bully dog chip ruining the tranny? how?

 

IMO BD is nothing more than computer hackers rather than Performance tuners. They would be my last choice of any brand of tune...

Seen more down motors running their stuff than anybody else. The Dodge guys seem to like em though.

 

Don`t know....... just heard but no explanation, and I couldn't find anything good about Bullydog in FTE so I did guess people stayed away from it.

 

what seems to bee the problem with BD?

 

Usually, the 'ruins the transmission' claim comes from people running considerably more horsepower through a tired old stock transmission that fails a while later. A tuner, in and of itself, should not 'hurt' the transmission. If you drive anything like you stole it, the transmission will suffer.
