Maybe the computer can make the adjustments off the MAF? I'm a big chicken and would rather tune it than break something.  |
I'm not exactly sure. They got to 560 at the wheels and it was apperently 104 degrees in the shop and he told me he could easily get 580 in the morning but wanted to keep it safe.
But he had dynoed it with the bigger pulley the first time and I told him I think I want to go with the bigger pulley to be safe. Eventhough I'd leave power on the table and he said why don't I just get both belts and pulleys.
I asked him specifically about having to have it tuned for that and he said no.
