Ok, I'm getting real close to boosting my 420a, It's fully built with a Slowboyracing bottom end all forged with 8.8:1 comp, ARP head studs with a Cometic head gasket, Ported and polished head with bigger valves and stock cams for now(Crane 16's goning back in), Ported and polished intake manifold, 60mm TB, AFX Race ECU, Solid front motor mount, Rear mount with the poly insert, Southbend DXD-F clutch with the SS pressure plate, and a Phantom grip LSD.

Now when I boost it, it's a custom setup with a Garett GT28/71R with a decent front mount intercooler and it'll prolly have a intercooler spray bar. I'll prolly have it set a 15psi most the time maybe 20psi for the track. Now what I'm wondering is, or would this work. Install the Apexi SAFC for the fuel control, and install the programable MSD DIS-2 that has the Timing retard for boosted aplications. I know the AFX ECU advances the timing and down low thats good till boost hits but then you want to take that timing and pull it back out as boost increases. So do you guys think the Programable MSD DIS-2 with a SAFC could handle the GT28/71R at
15-20psi ? Any input on this would be greatly apreciated
