DP Tuner is in my van!!!

I got the 80 econo and 120 race. Wow! Stock with only a BTM-I would get 13 lbs. Now it spikes to 25 instantly on the 120 race setting! But then the ses light comes on and boost and power drop way off. I am assuming (hoping) this is because of the overboost and the pcm defueling and not the hpop, so I ordered the annihilator from itp last night.

If you disconnect the f5 switch while the engine is running, it is supposed to hold whatever tune it was on, correct? Well I did this and the engine died. Plugged it back in and it started right up. Upon further inspection, there is a red wire that loops into a piece of shrink wrap that is disconnected, broken. I assume this is the wire that tells the pcm to hold the tune when the switch is disconnected? I taped the switch to the plug for now so it doesn't come apart while driving.

I will call Jody on Monday. I was careful routing the wire to the hole I put in my dash, so I don't think I broke it during install.

Not sure on your question, but congrats on the new found power

You can't pull a chip and have the tune you pulled it on to still work, if you do all there will be is the stock programming. You're not supposed to take the chip out while it is running, that might severely mess something up. You can shut the truck off, etc. etc. then pull the chip, not while it is running.

If you had a programmer like an SCT, or an Edge.. it overwrites the computer whereas a chip just is a piggyback if you want to be on easy terms.

i agree with dave.... dont unplug it while your engine is running...

No-you guys are misunderstanding. I am talking about the switch on the dash that changes tunes, not the chip itself!

I don't know where I got that I could remove the switch while it is running!!!!

Rereading the instructions, removing the switch will make the chip default to position 0, which for me is no start. That would explain why it dies.:bonk: :bonk:

So maybe that red wire isn't supposed to go anywhere.
