Question: go faster?

i need some info on re-mapping (i think thats what it is called)your computer. :confused how does it work and is it bad for the car? back in the day it was just putting in a chip.

Today its called "getting a tune". It can be bad if done wrong. If done right you can pick up a noticable amount of power. Multiple data tables are adjusted and the changes can be made specifically for your car - instead of general changes like the older "chip" replacements did. This is best done with the results checked on a dyno at the time of the "tune".

The computers in new cars are a lot smarter than the old ones, they are able to sens changes the chip made and over time will adjust themselves to original specs. Dyno tuning will produce best/safest results that will last.

The above is not correct. Lilke the older 81-93 Vettes, which had the ECM calibration in their "chips", if you reprogram the calibration in a 94-10 Vette's ECM, the change is permanent until you recalibrate (reprogram, reflash, "tune" or whatever). The ECM has some "learning" ability but that does not extend to changing the calibration.

Where would I go to have this done???? Dealer or a speed shop

I think the Op was referring to a chip you plug on top the ECM (old school) and was not referring to changing parameters within the ECM. Such chips are worthless because in time the ECM will adjust for preprogrammed AFR, timing retard etc. ratios.

they are able to sens changes the chip made and over time will adjust themselves to original specs.

The ECM does not actually sees the chip but it will receive different inputs from O2's and other sensors and will adjust timing, air/fuel ratios etc. in order to keep the engine operating within preprogrammed parameters.

To OP, get it dyno tuned, that will include reprogramming the ECM with new values that will stay there till you change them.

I'd say a Corvette Specialty Tuner!

"Back in the day" it was called building your own engine, etc.

These days we use our laptops, connected via an adapter/device, that allows us to tune using HP Tuners, or that ilk.

You can, assuming automatic transmission, adjust torque limitations, shift points, shift pressures, rpm limits, tire diameter, short term and long term fuel trims, knock retard, the list goes on and on.

Can you screw it up? Yep, but you can UN screw it easily too.

This is how you LEARN about your car, rather than just driving it.
