The Tune by SVC

[TurboEd]

True. If anyone says "nigt and day" etc. Beware.

Yeah, I fell for that once. Not again.

There are significant improvements to be has by tuning. There are notable differences from tune to tune. 5star tunes are very good IMO. The SVC is what I'm staying with. The 5star 93perf maybe for trackday photoshoots (chase truck).

That's subjective...

Improvements to what?

If we're talking pure HP and TRQ significant to me would be around the 50/50 to the wheels range.

If tuning alone can get me that - for that bang to dollar ratio - I'd be all on it.

I'm wondering if the old intake + exhaust + tuning upgrade kit will get you 20 HP.

If we're talking general daily drive-ability of the truck then you might have something there.

I understand that manufacturers tune VERY conservatively and that some improvements can be made. But, if you're looking for power you should just go FI. If you're going to stay NA then you have to do some serious engine work a la Livernois etc.

How's this: Keep your fingers off my tone, friendo. You've got your own tone to worry about.

I just loaded svc tune on the truck with phase 2 roushcharger and already have noticed a great difference especially in the shift points and how smooth. Which I feel is a pretty big deal with the added power. Doesn't feel like I could leave the tranny laying on the dirt behind me. All and all I'm very happy with how the truck performs so far!

It seems to be making more power with the tune alone. Nothing big though. Would have to take it to the dyno and measure it to be objective.

What do you mean by 50/50. You mean a gain of 50whp and 50wtq?

Here is the dyno graph with the A/F ratio for the SVC calibration on a stock 6.2L.

With regards to some of the other questions by Ruger, we haven't seen any negative effects on Cylinder Head Temperature, Exhaust Flange Temperature, Catalyst Temperature or even fuel consumption due to the efficiency of the tune itself on the engine. It's also important to note we only increases the power output when it is needed (WOT, towing, uphill pull).

If anything the Truck may run cooler due to the Fans being turned on at a lower temperature than stock, depending on individual driving style, fuel consumption may also be increased due to the advanced transmission shift schedule that has been recalibrated, but that is all dependent upon your right foot.



Now whats funny, and I've been waiting for someone to catch on to the fact the increase in HP numbers have been for all to see since the day we launched the tune.

Notice the graph in the launch picture



Anyway, I'm glad those that have stepped up to the plate and uploaded the new tunes are satisfied with them. As I said before. Drivability is the name of the game here. On a N/A engine, hp gains are usually very nominal at best, that is why we focused so much time on shift schedules, when the power comes on and cleaning up the engine mapping as a whole.

Thanks Jarrett

That is funny HP/TQ right there for all to see and not one mention. I am shocked I did not see it myself. I think most of the people posting are interested in the drivability vs. the power gain but that looks like a nice gain for NA motor.
