I had my car dyno'd yesturday after my header install and I put down 314 hp and 304 torque. He said I should be around 330hp if the converter would lock up. Is this true and how would I get the converter to lock up. It was a mustang dyno also.

My mods: Dacco 3200 stall, 3.73s, Voliant CIA, Edelbrock LT (victor series) y-pipe with a XR-1 Borla muffler, tuning: HPtuners

I had the same thing happen on my car.Your tuner can make the converter lock up manually in any gear. However some converters will not lock up unless your on the road.

Manual lock up switch. You have to splice into the wire off the back of the pcm that controls the lock up. One connection on the switch goes to the wire, the other goes to a ground. It will throw an SES code when you lock it up unless its programmed out of the pcm already.

I use the tech 2 to lock them.

Ummmmm. Who cares? Its an auto... They rule at the track - not at the dyno.

He has HPTuners, no need to splice anything nor use Tech-II, HPTuners has VCM Controls that allow you to lock the TCC when ever you want. Also, so long as voltage is supplied to the lock up soleniod the TCC will apply, regardless of being on the road or not. Lock up may not happen if you have misfires or the trans (fluid) is too cold.

Allright thanks guys. Regardless of the dyno numbers, I am very happy with the setup and power gain.

When they're locked up they suck up less of the motor's power. You get power loss from accelerating the rotating mass of the tranny internals, but no loss from converter slippage. It's useful to dyno like this to see if you should be locking up at the track, and at what speed.
