They already offer the acceleration boost for the Model 3 LR which then is barely slower than the performance model 3 (model 3 performance is only faster 0-30mph, then from 30 up they are pretty much identical)
The biggest difference is that they will almost certainly never offer the track mode with power split adjustments, turning off traction control, drift mode etc.
I absolutely think it’s feasible for $5k or so they will offer a boost to maybe get the 0-60 to 2.8 or something similar. Would be a lot of free money for them from ppl who already purchased the LR.
