Is an SCT Tuner worth it for a Stickshift

[Airmaster]

Hey I'm considering getting the SCT tuner but I'm hearing tuners don't do much when you have a manual transmission...

Would it be worth the money to get the SCT for my stickshift?

Another reason other than performance is that I'm installing my 29 inch tires on my truck tomorrow, up from 27 and I would like to tune the truck so that my speedo will still be correct.

Can an SCT tuner account for bigger tires to get the speedometer back to the correct reading?

I have a 2006 3.0L if that helps.

Thanks or any advice ya got!

pretty sure it can. Idk about the performance aspect though

Well that may be enough of a reason to get it, I'm sure a dealership would cost a bunch to reprogram the computer for the tires anyways...

you should be able to adjust for tire size and axle ratio changes but the performance aspect of those tuners i haven't dealt with.

My programmer was well worth it for my 4.0 SOHC Ranger with a manual transmission and I can't even recalibrate the speedometer. My programs were done for me. Not only do I get better performance but the truck has better drive-ability. If I can control my lead foot I can also get better gas mileage. I had the speed limiter raised too because I don't like being limited to 90 mph when I am passing on a two lane road.

An SCT X3 has options to adjust global spark, 0-2000rpm spark, 2K-4K spark, 4K-8K spark (these are all timing advance/retard values) ability to increase WOT fuel (but if the loaded program is worth a damn it should be calibrated already) rev limiter, speed limiter, gear ratio, tire size (in revolution per mile) and for auto trans you can increase line pressure and shift points.

I ended up installing a cat-back and volant intake. Talked to FRED at rogue performance and I ended up with a "base tune" where I datalogged the engine for a few days and he made adjustments necessary to bring it closer to perfection. It does provide more passing power.... but its not going to make a 3.0L perform like a 4.0L. However, it will allow you to account for axle ratios and tire sizes.

Plenty worth it. Depending on the tuner you can change speedometer calibrations and the other important part, tune your engine for performance addons. Get it now when you have a use for it, keep it for engine upgrades. You never know when you will need it.

Thanks for the tips everyone, I think I will look into it, is rogue performance the best out there for the 3.0? I know I've heard the name mentioned on these forums before...

I would use Fred. He's done some wild things with a 3.0L so he should know what to do with your setup. I got a few ideas from him for my old 3.0L including crane 1.7:1 ratio roller rockers originally made for the 5.0L mustang.
