This morning it was cold and when i went to start my pickup it would start then die. It did this three times untill it started running. i have nonly noticed this problem ever since I installed the Predator performance tune. Could this mean with the tune it is running too lean or what? I took the tune off and will see if it starts right up tonight.

It fired right up tonight with the factory settings restored... any ideas???

Can you get it running with the tune installed? It wouldn't be a bad idea to check the real time data with the tune installed to see what your sensors are saying.

yeah I can get it running with the tune installed... But once it starts running it's fine. I cant think of any other reason why it would be dying. It turns over, cranks, runs for a second, then dies. after about 3 times of this it will fire right up. I have an 87 chevy silverado that starts better than this one!!

This is strange.
Do you get any codes with the tune installed?

Thanks

no there's no code... I reinstalled the performance tune and it stil has trouble starting if it is cold

I'm really worried about it tearing up my truck . I might just unlock my tuner and sell it. It's not worth having to buy a new engine for that little of performance .
