My E46 Tune
To start off I only have a 323i so I wasn't looking for huge gains here. Just wanted a little extra pep if you will.
Tune was done by Mark Dasilva. I have seen a lot of good reviews on his work so gave it a try. Dropped by his place over the weekend and he answered all my questions before we got started.
This guy deserves his reputation. I feel a noticeable gain in gears 1 to 4. Car is definitely more responsive and has consistent power delivery through the rpm range. I already have a conforti intake installed as my only other performance modification.
To add, he was real easy going and knowledgeable. He even offered to restore back to stock if I wasn't happy with the gains, what more could I ask for .
