How much was and how much is? (before, after)
Boss, with the number you posted, I'm expecting near 700 HP for S63tu if they can crack the ECU
|
700 HP is on wheels(whp) or on flywheel?
Boss, u r upgrading too? If yes when is it coming? Did someone say the 1st week of sep? |
I'm not doing a tune at the moment, but M-bitious has posted that he will try this in september.
All the euro tuners quote flywheel hp, so I'm pretty sure that's what they refer to here as well.
