two yrs ago I done the SERT and have had to pay for two dynos since them about 450.00 and that adds up. done stage1 at 1k and then cams at 16k, this is probably the last time I change for a long time, till top end job needed, then another dyno, now total will be about 650.00-750.00 just for tunes.
If I done it again I would look at the others where I didnt have to pay every time I changed things....but the new and different systems are getting better and more to chose from..
I paid for a dyno tune $280 and had rush slip-ons $240 and a PCIII that I got used for about $170. I was happy with it but would have spent the money for a Thundermax if doing it again. but when hooker had the pipes 75% off and spent $200 for them. now I would need another dyno tune $320 but I found a used Thundermax for $450.
I sold the used PCIII for $170. so lets see I have $890 in it. well that is about even. for all you who hear all the rave about all the fuel management take it from the silent ones. The Thundermax is the way to go.
But I came up with a cheaper ideal. The stock 02 sensors are about $25 each and are made to switch at 14.8 and have a window of 14.2 to 15.2. If I can get someone like bosch to make a set that switch 13.5 for offroad use they would replace the stock ones and would put the fuel back to the old days. the narrow band would still retail about $25 each. maybe get them made for export only and offroad.
I picked up my Bones late yesterday and all I can say is that it's like an entirely new bike with the T-max! Unbelievable how well it now runs. I wish I would've gotten it from the beginning but live and learn I guess.
I've had mine on for a couple months, love it... had a pcIII, paid for 4 dyno tunes and still wasn't happy... first ride with the tmax the difference was obvious... I did adjust a/f ratio on mine yesterday, just to see what effect on fuel mileage, ridability, etc it would have... I've changed pipes and air cleaner since I've it had so I figured I've got my money back already by not paying for tunes...
Have an 08 fatty and running a stock air filter and BSS… dealer told me as long as I didn’t change from the stock air cleaner I wouldnt have to worry about fuel management. Well I have a little deceleration gargling and the occasional backfire… but doesn’t happen to much…
So where can I find a cheap thunder-max? Sounds like that will take care of the lean running engine… coming up on 5000 mile service, will have the dealership check the plugs and see how white they are if at all.
