Hydro-Tec and Simon must not be speaking. I remember reading that Simon cracked ALL of the Yamaha boxes (including the Waverunner and Sled boxes) but I assumed the not HPDI box because of all the talk of it from HT customers.

Well...since Simon has done it than it must be easy :roll:

...go ahead...buy the ebay box :mrgreen:

yeah i have spent hours reading about people talking about the limiter on the HPDI's.. according to HT who knows if this is right but the HPDI's are on a power curve that shows "if " they were to get past the limiter at 6500- 7000 rpm they would make big power. i wouldnt buy the box.... i'd get Simon to do it.

Depends on the model...they all got new oil pumps and some got stronger internals....as I know there was no performance difference between the two.

Edit...I think the 300 got something to make it more like a 300. I remember them raising the recommended RPM to a max of 6k over 5500 or 5800. The Series 1's turned that fine anyways so I don't know if they actually made a change or just changed the literature...
