[fx4sandtoy]

I have a 05 f250 td.It's got a banks monster exhaust & airaid intake.Recently installed a bullydog power pup running it at 70 extra hp.now my speedo dont work and I lost about 10 psi of boost.All the dealers keep giving me the run around.Anybody having the same issues?

what does it do without the power pup?


did you take in to the dealer with the pup installed???

Speedo still doesn't work after I removed the bullydog and still have loss of boost.Yeah,I removed it before I took it to the dealer.

Boost leak somewhere maybe for the boost problem. The speedo speedometer cable intact? Just a couple of thoughts. Any codes?

is it just your speedo that is going out?

with the bullydog plugged in,my dash tells me to "check gauges"."TBC fault".Im guessing the last one is a " turbo boost control fault"My speedo is the only gauge that doesn't work.When the motor is cold I only get about 23 psi of boost,after it warms up it goes to about 19.I usually get about 28,29 psi.

I have an 06' F250 PSD and have the same problem. I have replaced the instrument cluster and VSS. No fuses are blown and all relays are good. What can I do? I have not yet brought to Ford dealer? Have you solved your problem?

Thanks!
