I'm trying to perfect my new '02 Bugeye. Keeping it mostly stock for now. I installed a Grimmspeed uppipe to avoid crap in my turbo. Now I realize I need to fix the fuel lines under the Turbo inlet tube. In order to do this I will be getting a Perrin replacement to avoid intake removal. My question is, would I need to have any tuning done for these two upgrades? I've read that the uppipe does not require tuning and I'm hoping for the same news with the Inlet. Thanks for your help.
