How can you say the tuning potential for the HR isn’t as good as the DE? We haven’t even seen the beginning of aftermarket mods for the HR yet!
And keep this in mind, too: the HP and TQ ratings for the HR are with the new, revised SAE standards which are designed to be closer to actual HP at the wheels (i.e. lower than before). So, under the new system, our DE would have less than 287 HP and less than 274 TQ, or the HE would have higher than 308 and 268 under the old system.
