I have a 02 ALH Jetta, 11mm pump from 5-sp-swap, No other mod's. I am getting ready to install PP520 Nozzles, which as I have read can be put on a stock 5 sp, without tune/turbo.
I read that I should upgrade my MAP sensor to prevent overboost, but read somewhere else that with a 3-bar MAP I would be more prone to overboost. So, which is it? Do I or do I not need to upgrade the MAP sensor? Can I drive it with out upgrading the MAP? Any other suggestions besides a Tune?
After the nozzles, I am cosidering upgraded exhaust. Would this be premature? should I wait for a tune and turbo before upgrading exhaust?
Thanks For the Help..
