rcd tunes

[Rocken1]

I've read the past post on there tune thinking of ordering from them I did see the tuning levels have changed though that they offer. I'm thinking of going with the 550 tune. I was wondering how every thing was holding up for those that have rcd tunes and any thoughts on the 550 tune. thanks

Everyone has good things to say about them. There is only one guy that I know of that has problems, and he has had problems on 2 trucks. Both of his trucks got a lot of miles with the tunes, probably more miles than most people running RCD tunes. I am sure something will come out of his issues, we will just have to sit back and wait. Other than that, they have a good reputation thus far.

I have the 485 and the 585. The 485 is a very smooth and strong street tune and will dust just about anything on the street. The 585 is a total beast and is only for crazy people with a need for speed. I dont know much about the 550 but you can e-mail Brad at RCD brad@rivercitydiesel.com and he will give you the 411 on it.

My buddy with his spartan tuned truck drove my RCD 485 tuned truck this past weekend. Within 10 minutes he asked me if he should by a SCT just so that he can run the RCD tune. He said its strong and shifts nice. His comments were, "I am getting tired of the harsh shifts from the Spartan 275 and I cannot seem to do anything without the exhaust temperatures going through the roof"

I rode in my buddies truck as well this weekend first with the 485 and then 585. Truck runs great no doubt. I would put my truck with the 275 up against his 585 in a heartbeat. Granted my truck has stock radials, suspension etc and he is running 38's with a 6" rise. I don't want to hijack RCD's thread though. Just my .02.

On another note though, his 485 shifts VERY smooth. Similiar to the 210.

Thanks for the info. On the rcd sight they offer the 525 550 and 585 there is no 485 listed they changed the menu I was thinking of going with the 485 and 585 but maybe the 550 might be the happy medium for me next week I'll be ordering it.I did call them today and they were very helpful with all my questions.

I have driven his truck as well. Powerwise, the 275 has more than the 485 whcih it should because the math tells me that 485 would be more comparable to the spartan 210. Shiftwise, I like my RCD. As mentioned, the shifts are harsh on the 275 and I could not get to speed with the 275 without the temp going through the roof.

The RCD tuning is nice. I have plans yet to buy both the max economy tune and 1 hotter tune most likley also with a lope.

I see they did revise the power ranges that they offer but you should still be able to get intermediate tunes. The 485 was never published before, it was simply the 450 pulling more fuel. When I ordered it I was told it is the cleanest tune they offer with the most hp that will not cause any reduction to the life of the tranny.

I have personally never had problem with the 275 tune EGT's, and EGT's going up really high for a short amount of time is not something to worry about as long as it isnt held there for too long. I couldnt imagine how hot the lope RCD tunes are. Probably as hot or hotter than the 310 Spartan tune. As far as shifts go, it sounds like he has a job 1 TCM.
