I'm looking for JUST the chips for a 551A ecu(s4 but I'm running it in an S6).
Stage IV/V. I've got Pastore RS2 set right now but it's a little ping-y.
I have RS2 Turbo, Manifold, MAF, Cam, Injectors(dekas, I think. I'll have to get the part number), Stromung Exhaust and I'm looking for a 93 tune ...

This is great. Thanks.
