hey guys. I initially posted this in the tuning forum but I think it belongs here.
I have an 05 GT. Had an STI up and Perrin catless dp put on plus a dyno and street tune.
The torque/power was amazing..lets say a "10" vs stock.
The problem was I have a 5EAT but the dp was made for a manual tranny. The dp rubbed on the firewall and against the tranny pan causing ALOT of noise and vibration in the cabin.
Today I dumped the Perrin and had my tuner put a beautiful fitting new invidia dp on.
All vibration and noise is gone but so is some of my torque. Now I would rate it at "8".
I'm assuming the loss of torque is because the invidia dp has a much sharper bend coming out of the turbo vs. the Perrin and this is resulting in a lower amount of air flow?
Do you guys think a street tune would bring back some of the lost power?
I love the new smooth quiet ride but man...I want that lost torque back!!
