    You will have to correct your VE table for your GT42R.

    Ok i havnt touched this in ages and started tuning again last week, went to the drags on sat
    On the street it spins the tyres easy but has lean spikes everywhere under boost
    On the track with slicks wouldnt rev past 4600rpm and had lean as much as 18.5 under boost, no good...
    Need serious help with this

    I hate reading through a thread and it just quits. I'm sure the OP does too. It's like the movie just stops half way through.
