^^ what is the expected HP increase with the PPK? In the past the gains are only up to 335is specs which is only 320hp.
Turner is willing to do $1500 for the Hartge tune when i emailed them. Still a lot of money for a piggyback system but looks like the only option at this point.
You can NOT compare JB to Hartge. Hartge is in a completely different league as a Bmw tuner in Europe
