Hey guys, I bought a pro tune from DIzzy for my S280 and I'm still on the low boost base map since I got it installed last Tuesday. Anyone who tuned with him lately able to comment on the average turnaround time? Spent nearly $4k and I'm driving a car that is slower than it was at stage 2. Not even having my first revision at this point is generating some frustration. Thanks for any insight you can offer!
