Agreed. I ran a 125 HP shot (NOS direct port) through a couple of bottles with no issues using the stock tune.
FWIW, I also had a KB BAP and a Plasma Booster, along with colder plugs closed up a bit. You will be safe if you don't beat on it, use a WOT switch and window switch. Take care of your equipment and it'll take care of you.
BTW, 75 will get old...it's never enough. Just use your head, data log if you are able (I also ran a wideband and did some datalogging before and after), and don't go through the bottle in one afternoon...!
yeah, like the others said, use some colder plugs and fill up with 91/93 octane to prevent denotation. The window switch seems to be popular because of its safety feature. If you dont get one right away, be careful to mis-shift....or better yet, its funner to use in the third to forth gear pull .......i cant imagine someone missing that shift lol.
