another way i see it.
stage 2 on average yields around a 20hp gain over a stage 1 map.
stage 2+ on average yields around a 20hp/20lbft gain over stage 2 map
on a non PDT map(like the low powered revo variety
) your looking at 240hp @ stage 1( with intake), 260 stage 2 (with an intake and exhaust), 280hp stage 2+(with intake, exhaust HPFP)
on your PDT map your on 258Hp stage 1, so stage 2 from above would be 278hp and stage 2+ would be 298hp
hmmm...
