Hate to start ANOTHER thread on this...

But I've been doing a LOT of reading and searching on this subject. I'm getting a SCT SF3 with the head studs and all of hte other work being done on the truck right now. I believe my dealership goes through River City Diesel... I am mainly looking for mileage increase...but I tow under 10K often enough that I don't want to be switching tunes back and forth. I am looking for good driveability (Something that won't kill my girlfriend also when she drives) and mileage. What's my best bet? There's so many options out there, I don't know where to start. Anybody ever used River City Diesel custom tunes? I need a little advice here, if y'all don't mind. Thanks!

To get the best mileage you're gonna want to run a high power tune. Thats what most people experience. As for drivability I hear Matts SRL is the smoothest throughout the power band. Its what I run and love it, but cant compare it to any others, as for a tow tune most guys have a tow tune as well, Matt has a 8k/10k tune. Its recommended 8k for non studded guys and 10k for studded and I think its about 65 hp. There is something to start you off with and I'm sure someone else can add more.

I have to second the recommendation for Matt@ Gearhead. Driven trucks with custom tunes, but Matt's seem to be the best!

Thanks for the info guys!! I really appreciate it! I didn't know if it was possible to tow in the SRL tune or not... I just never know when I'll hafta run home and grab a trailer and go do something and I don't want to be switching tunes all of the time. I don't tow heavy loads all of the time, but occasionally I latch onto something memorable, lol.

As long as your smart and watch your gauges you should be fine. I wouldnt tow heavy on a regular basis with it but doing so once and a while and being smart about it wont hurt you.

Like he said, I wouldn't make it a habit towing with the srl, but as long as your not doing any hard accelerations, 0-50's next to a ricer, and you watch your egt's, I would say your fine...

Although everytruck is different, if after the first time you do it. You find you cannot keep your egt's at a safe level, I would say you should t do it at all.

I'll definitely need to get a probe for the EGTs before I'll feel safe. Someone told me that the Back Pressure sensor could be used to calculate EGTs? Anybody know anything about that? Thanks y'all!!

Wouldnt rely on a sensor(EBP) sensor to guess at EGT's. You need to have a data monitor on that truck even without tunes. I would recommend the Edge Insight CTS for data. Its freikin awesome! You can hook EGT, backup camera, and all sorts of other sensors. Best data monitor on the market IMO.

Yeah, I'm really wanting to get the CTS asap... That thing has a lot of neat features. I'm gonna try to pick one up in the next few days....
