Custom Tune Question

**BigHemi06** · 05-07-2008, 12:30 AM

Looking at getting a cam installed soon with Longtubes, exhaust and air hammer, already have the predator....now my question is I also have a torque converter that I will be putting on in a month or so after...should I wait to do the cmr tune after the torque converter or will it be ok doing the tune before the tq is installed??? Thanks for the help

Tuning before the converter is fine and you will not need a retune after its installed.

You will most likely see better HP numbers on a dyno with the stock converter because you dont get as much slip. The aftermarket torque converter will give you better numbers on the track.

Yeah, i see that all the time and customers get disappointed he he.

You'll get a better tune with the tight converter.The dyno will have more control of the motor.Manual transmissions are even better.On a rolling dyno you can't simulate a launch.The lower the tuning rpm the better for flashing the loose converter with sticky tires.

I think that made sence?

ummm maybe try a word the last half a little differently....a little confused on that.

Ok
In order to get good AFR numbers you need to stabilize the engine at each rpm step so the Accelerator pump function doesn't skew the readings.The better your motor is tuned in this area the better it will respond when loaded hard against a sticky tire.Some cars will blow away a street tire then fall flat on they're face with a good tire.

Hope that makes more sence
