It raises the limit a little. I think to 5800 or 6K. The shift points are the real limiting factor. It'll only ever hit redline if you manually shift it. It has a ignition cut limiter, so you WILL notice it if it hits it. Mine is at 6200 IIRC but the shift points limit it to 5800. I need to reduce it a little since my old exhaust is limiting things and it starts to wheeze above 5000. But I just let up on the gas to let it shift and then get back into it. There's really not a whole lot of difference between 2/3 throttle and full throttle. The real "feel the change" is between 1/4 throttle and half throttle. Stock vehicles should handle 6psi boost with no issue. So yeah... no worries on a basic naturally aspirated tune.

get a rear sway bar first. change one thing at a time and then test. Then there's no question if something made it worse. Also, make sure the alignment is good, suspension bushings/joints/steering bits are good, and the tires are decent. Sloppy suspension/steering joints will cause no end of suffering. They should be stable at 100mph. If the ass is sagging, that will be an issue. The rear of the car should be about half an inch to an inch higher than the front. If the rear is lower than the front, it will catch more air and float the car at high speed. My 93 has never floated at speed and I've had it up to 100mph for extended runs here in Texas out in the boonies on the interstates. No issues with the nose floating. I did one run with the wife and kid and my cargo carrier (truck box mounted on it) on the hitch with a good load (I do have load helpers too and that made the car maintain level) and had no issues keeping it straight. I was following a late model charger that was cruising. I kept my distance (about 500-1000 feet) for about an hour before he turned up the wick and left me behind. Caught back up when we got to the big city and hit traffic. They obviously didn't turn the wick up too far. But yeah... about 2 hours between 90 and 100 with zero issues.

Throttle body spacers do nothing, throttle bodies do though. I had a 75mm on my 02 gt and it made a difference but it might be overkill for our cars.

I paid a shop to weld mine on. Need to get the tails opened up for better flow and headers. Everything else in the middle is free flowing already. I did use magnaflows though. I like that sound.

Mustang shorties work with a little modification to the down pipes.
