I prefer the way that Twisted & Cutler do things myself, but it really seems like all of them are pretty dialed now. Bgraff on here has a cutler PC turbo, maybe he could offer some insight to how simple his experience has been, but my last couple have been stage II cutlers & they've been more reliable than any other sleds we've owned.
i sure do have a cutler! lol. i have the cutler stage II with the 2871 turbo. i cant state anything about the other kits as i have no owned them but i have zero complaints about cutler kits. the fit and finish is awesome and the install is pretty dang easy, just take your time (seriously, no matter how exciting it is take your time, i learnt the hard way...). i will go through all the problems ive had:
1)first ride out on it i popped a piston, was able to ride it the rest of the trip as the damage was not that bad. anyway, got it home and tore it apart to make sure all the wiring was ok and decided to check the plugs. mag side ok, PTO side plugs didnt even have electrodes on them anymore.
. dove in deeper and found the head toast, PTO piston and cylinder done. found that my boost reference line for the attitude box was not tied down well enough and it got melted from the pipe (remember what i said about taking your time?). this means the box would never see boost and never would add fuel. hello lean condition. why it didnt burn down both sides is still a mystery to me but i re-did all the wiring and hoses and got it built back up
2) went to take the sled for a rip at home and only got a few hundred feet and it died. pulled the cord and fired back up so i went back. checked fuel pressure and it was really low and bouncing around, fluctuating 9 PSI. checked voltages and they were fine with the pump unhooked but as soon as i hooked the pump the voltage was very low. so i think fuel pump is done. manually tested pump with 12v battery and it works fine
. hooked back up and doesnt work. WKM got me a new pump next day, threw it in and it worked fine. sent the old one back to CPC, cost me nothing, great service.
3)next trip after fuel pump replacement. go to do my first pull and sled hits DET sensor at 8lbs. adjusted fuel settings and same thing. lowered boost till it was a low as it could go and still hitting DET. pulled plugs and they are white. uh-oh. checked fuel pressure-ok. checked lines-ok. everything is checking out ok. rode the rest of the trip at min boost worked alright. got home and checked motor out and it was fine, sweet! checked over all the wiring and it was fine. then i notice two connectors unplugged by the fuel tank. i was unsure what they were for so i snapped a pict and sent it to kerry at WMK and his exact reply was "thats for your fuel pump! have you been drinking?!" lol. anyway when i changed the pump out this harness fell behind and i didnt notice so when i hooked it back it it was running "stock" secondary injectors would not fire resulting in loss of fuel on boost, thus the DET warning all the time. (again on taking your time)
those are the only problems ive had. i am now running 10-12 lbs all day long and have never had a bigger perma-grin on my face. all the major problems were because on my own lack of inspection and double checking. the only manufacture problem was a fuel pump that cost me one not so good day of home riding. so is my turbo reliable? Hell yeah! am i reliable? that is certainly questionable!
PS: I havnt blown A SINGLE belt in the 700 miles i put on this sled boosted
