hey guys as some of u know i am putting a twin turbo on my all stock 98GT including NPI heads...and i want to be around 375HP with a safe tune...so im wondering how much boost u guys think i will need to reach my goal? my installer said it should be pretty safe up to 10lbs and after that he thinks it will get to much pressure in the cylinders being NPI and therefore being unsafe? so were gonna start with 8lbs of boost and go up to 10lbs to reach my goal...what do u guys think, will i be able to reach it being NPI and still being safe? i ask this because i have heard some supercharged NPI GTs being lucky if they reach 300HP
