Exactly. Literally every FI person I know that actually tracks these cars hard has had issues, whether it be heat management related or engine randomly externally venting itself related.

That will be hard. NA these cars start to drop off pretty hard at 6900rpm. 155wtq at 6900rpm is 203whp about the highest i've seen possible so far.
Now if you could drag that out another 600rpm and still make 155wtq but at 7500rpm it would be 221whp. I think the only way to keep power up that high would be ITBs or maybe shorter runners on intake manfiold, and a ace150 header, together i could see those holding power to maybe 7200rpm or 212whp. Then toss in cams and some oversized valves and you could probably hold power to 7500rpm and make 220whp. to go any higher you would need more displacement I.E. stroker kit.
