The Nine ball AEP upgrade springs only gave me 240 FPS with .2's (up from the stock 200 or so FPS). there's really not enough aftermarket support to make the AEP's even close to your 350 FPS goal.
For your Echo 1 G36/SL8, it probably already shoots 350+ FPS so like runchmeister mentioned, upgrade the other parts (barrel/hop-up/bucking) for accuracy. If you're looking to up the RPS, a new motor and battery would do wonders (especially if you're still using the crappy battery the Echo 1 came with).
