The IL is better:

keep in mind nitro's "normal" velocity (mech speed holding "b") is non optimal when going through halls and the like, if its your first tas you shouldnt be forced to keep it optimal, but you should give a try to keep it as high as possible (dont hit obstacles, release the gas for some frames, thats's what i got from soulrivers wip topic)
trick 1: reverse rocket, hit with a rocket as you fire it, so you must hit with your back, see my 7-1 I reverse rocket a havok, at 6-2 i hit the boss with a reverse rocket once. It does a lot more damage.
the boss at 6-2 would be faster if you tas every rocket hit to be a reverse rocket
trick 2: backwards walking. Press left + right and you can move facing backwards so you can shoot behind you. I think it will help vs the final boss and can help with "entertainment".
trick 3: invulnerability. Leave your suit (select) and enter it again. if you do it right you cant be damaged. Although you cant move either.
trick 4: mine boost. Be inside a mine when it explodes so that it launches you. Its hard to be in control of the trick realtime, but tasing you could manipulate it. Mines you can boost from at 1, 3, 5, 8, 9-1, there are also at other levels but I dont recall being boosted favorably from those.
trick 5: mega boost. This I got on a fluke. Didn't record it. Somehow get inside an enemy while they use a pushing attack and boost in that direction (I was falling and fell into a havok that was meleeing and then I jumped), if the timing is right you'll be launched at incredible speed.
trick 6: get locked in the final boss. The first two or three forms of the boss have a hole in the lower part of the suit where your mech can fit. If you get in there you get locked and can hit non stop speeding those forms. But maybe isn't faster depending on how it plays.
trick 7: 7-1 improvement. I leave my suit on the lower floor. You can leave the suit on the elevator. But it usually falls from it. Sometimes it stays onthe elavator. I dont know whats the rule, but I assume you have to exit the suit when you have 0 vertical speed.
