has anyone ever seen this before??? engine trouble now!
car was tuned to 15 psi of boost...
datalogged it since the engine is now smoking after one pull down the highway in third gear but noticed the rpm, tps were on the rise then the injectors went to zero.. what could have caused this???

A momentary lift, ever so slightly???
I'm no expert, but isn't your timing way too much. Either that, or my first idea is right......
anyone.
If that is your ignition at 15 psi, that might be why your smoking now.

but even though would the timing make the injectors quit like they are in the datalog???

What map sensor? Is that MAP reading in atmospheric KPa? If so, you are on the verge of maxing out your 3 bar map sensor, which is more than 15 psi.. If the reading is in atmospheric millibar, there is another problem.. Can we get a link to the complete datalog file?

To be honest, a few things stand out that would make more sense if we knew the engine setup and saw the calibration. However, it does seem a bit odd that you have 28 degrees of ignition at 13 psi boost. Also, for future reference, it might be a good idea to calibrate the tps, and try to stay off the rev limiter when in boost. If necessary, raise the rev limiter higher than 8500.

That's my guess as well.
