R class Viper

Running a Stock series with the R class Viper, Stock only
Next event YAS Full

I seem to be 3.5 Sec off pace (me at 2.13.5, faster guy at 2.10.00)
I know they guy is faster, but 3.5 is way too much , has me thinking my Stock tune is off

I do not tune, nor care too learn, I like Driving, not tuning. I am perfectly happy running the set up I have now.

BUT, if anyone want to help out with a Stock R Class #09 Viper, for Yas Full, That would be great!

I think its my Driving, as a Stock tune should not account for this much time.

Thanks
