hi new to the forum not so new to the game. i have a 98 olds intrigue with a gtp motor in it now with all sensors to go with. the 4t65e-hd, keep the stock olds final drive ratio (3.69? i for the ratio cant remeber) and some nice hard parts inside to. i have a c.a.i., hi-flow cat u-bend delet 3" down pipe, and cat back exhaust. just no pcm. i have heard different things from different people about the pcm tunes. should i start with a gtp pcm and have to final drive changed to match mine and all my mods. i plan to go bigger with everything that i can in the future. like bigger injectors smaller pullies. no turbo though, i like the sound of my superchager. its been sitting for about a yr now no time to work on it :icon_frow now i have some time im goin to get a pcm just what works best?
