I have an 04 Roadster & have 20" wheels on. When taking turns at high speed or even low speed the slip light comes on & it feels like it loses power like it automatically drops the RPM's. Does anyone know if that is normal for this car? I have a G35 coupe & never had this do that. Any information would be helpful.

 

Welcome. You provide little information.

Are the tires new? How many miles?
Do you have VDC?
What size are the tires?

 

The '04 ZRs didn't have VDC. Further to Davidv's question, your issue may be the tire/rim size combination. Is the overall diameter close to factory spec?

 

Sorry, I am new to these cars, I bought it with the 20" maas wheels on it, I will have to go get the specs on the wheels.

 

Most likely the problem you describe happens because the overall diameter of your tires is too far (different) from the stock measurement.

I had the same problem in the begining but GTM reflashed the stock EMS after I got FI and it's ok now.


I have 19" not 20"

 

... GTM... a dealership?

... EMS?

... How does one get FI? Is this Nirvana?

GTM= one of the best tuner in the WEST
EMS=engine management system
FI= force in duction(turbo, or supercharger)
