Then i would say a 57trim is a little over kill, A 16g or even a 20g sounds more like what you want. Keep in mind a 16g tuned right will make 350-400hp with good street manners and little lag. Or you can go to a 20g which is capable of 450-500hp with good street manners but a little more lag (not much). I have the 20g myself and im happy with it but then again im just know getting the car running right a like 3 psi
But i hope to push about 320whp when im done here which will probably include me going to a portfueler
