I have an early 99 PSD with a TS chip with TS tunes and am looking into getting some tunes from tyrant diesel. Just wondering what people think of their tunes and how did your trucks do on them ?? :ford:
Thanks for the info on tunes. I saw your signature and how did you make your overboost regulator/Boost Fooler ?
Alright i thought that some tunes did.
On the boost fooler subject.... I have been running 250/200s and 50# of boost for the last year now, never thought i needed a boost fooler.
Well i was wrong, installed one and the truck pulls harder, makes more boost, less smoke etc... Not like 50hp gain, but enough to notice.
Also had a bucking going on with some of Cale's tunes at higher altitudes, took care of that (defueling)
Its my opinion now that for the price of one, you might as well install it. Just for added assurance even if your not throwing a CEL
I find that hard to believe but I guess anythings posible. I still had one on my truck when I started running php tunes, no matter how it was udjusted never matered, ended up ditching it and never noticed a thing...
Altitude may have something to do with it, im at 4500ft right now. But I had tunes from Cale and TW and could get both of them to defuel up here, never would defuel down at home (400ft). Then i had them adjusted to try and get the defueling to stop with just tuning. That worked on some of the tunes, but every once in awhile i could throw a CEL.
PCM's are all different, my truck may be a special breed. Ive had to tweak lots of stuff in my tuning to make it run exactly how i want it to. I figure the boost fooler is just added insurance i can do whatever i want with tuning and never worry about a defuel or CEL.
A defuel feels like your floating a poppet or the truck is going to blow haha
