here's a little story for y'all. a few weeks ago when i only had the edge programmer on the truck with the intake, exhaust, etc.. i race a subara impreza.. don't worry it wasn't an sti model, but we stayed even til about 50 then he started pulling from me fairly hard.
now, with the stage 1's, i raced him again. this time there was no contest. from a 20 roll i pulled really hard from him right from the start and he never showed any signs of keeping up. we tried it from a 50 roll and although i jumped ahead about a truck length, he kept up til we got to around 65 then i blew away from him again.... so this little test really showed me how much difference these injectors made for me. with the warmer weather it's gotten harder to control my EGT's, but they are still kinda easily controlled unless i'm going up a very big hill. downpipe and cat delete pipe are on their way to my doorstep.
