    Debate on: Rpm or boost!?

    Which is the best solution as far as performance gain and safety of engine: increqse boost or increase rpms byecu rev limit?

    Put a big sc like 140 mm and go 8100 ecu or to go with 137 mm upgrade sc to 8800?

    Or could be the best to go 137 mm upgrade sc and 8600? It is safe but not good performance gain!!!???

    Your ideas?

    If the engine is tuned properly and all components are working properly IMO either way you should be fine.

    Lately people are opting for higher compression (9.5) pistons etc and using a med boost SCER like an X Charger and or ET137 etc. Many people have did this over the winter and Im awaiting their results.

    Oh and DONT skimp on the drivetrain. spend the money now for the Riva Valvetrain if you have not already done so. It could save you very costly repairs.
