00 grand prix gt, 2.5" DP, zzp powerlog and pcm, l26 uim swap, l67TB and DIY cai, but otherwise stock besides suspension. i was looking at the yella terra rockers on intense, and i noticed they now offer them in 1:6,1:7,1:8, and 1:9. I heard somewhere that the 1:9 is too much for the N/A motor, but i dont know if thats true. my goal for this car is to add as much fun to it as i can without destroying the gas mileage because its my daily driver. also, does anyone know what kind of gains an N/A motor gets from high ratio rockers? all the numbers ive seen are questionable advertising about supercharged gains.
