I did the 31h as my second engine mod, and it really woke it up and gave it a nice sound and lope. I cant recall if I was using the PC III or the TMax at that time, but whichever it was it worked just fine. IIRC, I debated back and fourth between the 31h and the 48h before I finally decided.
I'm not nearly as performance educated as most of these guys. But after looking, researching and talking to my Indy and few others, I went with Feuling Reaper 525s. They come alive earlier and pull longer thru the RPM range, 1,750 - 5,500. They were a perfect match for my application, I do a lot of 2UP touring loaded, so I the power kicking in earlier and longer. Dyno tune it properly, it made a world of difference. I had a canned Fuel Moto map in my PCV, but after I had it done on the machine, she was an all together new animal.
The Andrews 48 is a great cam, with many happy owners, if you are looking for a low/mid range high torque cam.
The tune is the question....
I know nothing about the V&H FuelPak Legacy or its capabilities. You should talk to someone in the know, (maybe call FuelMoto) about its abilities to adjust for your cam change.
The goal when tuning is to get max performance AND drivability from you mods....
Obviously, a dyno tune from a competent tuner is the best option for max performance and drivability...
I've had great luck with downloads from FuelMoto via a flash tuner (PowerVision)....
At minimum, you want a safe tune... one that won't allow the engine to reach a condition that can cause damage. Unfortunately, just a minimum safe tune won't give you the full benefit of your cam mod...
Someone who knows that tuner should be able to tell you what it may be able to do for your cam choice. Can it provide at least a safe tune or can it provide a good tune for your cam choice. Or... is it best to just leave the cams off your list of mods until you can get the proper tuner for a proper tune .....
I'm just concerned if I install them and maintain my current fuelpak system, how much performance will I get out of the cams?
Vh fuelpak legacy is a pretty basic tuner but I can't spend the extra $600 for a sophisticated tuner
As stated above, best bet is to save up until you can have it dynod. It is well worth the money, as the tuner should be able to adjust everything so that you get the best performance and rideability out of your investment.
