I've had both the Superchips and SCT on mine. Unfortunately, I never really got very far with the SCT before I scrapped the Jeep. Here are my 2c on them both though:
+ Fully tailored tune to your car so you will get the most gains
+ Tune can be adjusted with each mod
+ Ryan @ FRP is a brilliant guy to deal with
- Ideally you need a datalogger to get the most out of the tune (Look at Innovate LM-2 w/wideband O2)
- Not quite as easy as the Superchips to use w/regards to tuning the car
I'd recommend the SCT tuner if you really want to do some proper mods to your motor down the line (F&B TB, Cams, '08 HO Intake, or FI).
+ Pick the Performance or Towing tune and hit go
+ Cheaper as no data logger required
+ Great gains for a basic bolt-on motor
- Limited in respects to how far you can mod
- Set tunes which can not be customised
I'd recommend the Superchips if all you want to do is K&N intake/hi-flow cat + cat-back/ported TB. You'll notice the extra power, slightly better economy (when not planting it), from something that takes 2 mins to do.
So that's my 2c. Can't recommend one or the other depending on how far you want to go with modifying the motor.
Hey Marty, good to see you still on the forum.
Through additional sales and R&D on other trucks I've been able to further refine my 4.7 JTEC calibrations a great deal so the tunes have improved quite a bit since you and I tinkered with them. The datalogger is less of a requirement on trucks with combos I've already tuned now, but was recommended for Mark as he wanted an LPG friendly tune.
I know now that I can beat SC on any truck, both in power and mileage....Even bone stock...Hell, 4.7beast has just a K&N and a muffler, and used SC in the past. I have a known good calibration for bolt-on 4.7s, and should also have one soon for ported/08 manifolds.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
4.7beast; Fantastic, good to hear its coming together!! That's another reason I threw the towel in though! UK customs are a killer now and spending $5-6k at AirRam would have landed me with one heck of a bill! Plus there are few proper engine builders in the UK who I'd trust to do the work (boring internals to 5.0, installing ROSS pistons, SCAT rods... etc).
I know my Jeep would have been a complete frigging beast when completed but I spent £20k on it (only £3k in servicing though) in the 4yrs I had the thing - I saw sense and got out while I still could. Everyday I miss her though... When you put so much time/effort/money into anything you can't help but come emotionally involved (not physically though!! )
My SCT tuner & FRP tune went to 4.7beast on here along with my 218X cams that were to be fitted this year.
72mm F&B TB went to the scrap yard still fitted to the motor (as I threw the OE one out).
My baby was just the 4.7L SO. I did run the Superchips 91 Perf on 95 RON here but after working out PON>RON I quickly changed to 97/98 (BP ultimate/Shell Optimax). As you have the HO you've already got the better intake manifold ('08 is still better but you need to hack the firewall to fit it) along with the cams so just throw on a ported TB and call it a day. Exhaust won't give any more power really, I had a custom 3" powerflow system (hi-flow cat and cat-back) and it sounded great - see below YT clip.
I never got round to the shocks/springs but I was going for Bilstein HDs with Eibach springs from Summit Racing - never heard of B6s? sorry.
You can see some off Aaron's (StoneCold) excellent airbrushing work in the engine bay in another clip "Post Detail Walkaround Jeep GC" on my page - my only other video. lol
