It depends on how much free time I have. More than likely I'll do some 1/4 mile runs after the tune and exhaust are on, and have had time to learn. I should be able to compare my runs to the factory stats of 0-60 in 6 and 14.6 1/4 mile.

I installed the exhaust and the tune this morning. I haven't had a chance to really test anything out yet, since I also put my summer wheels on and have been waiting at the tire place for tpms program and balancing all afternoon. The ARK is definitely louder than the Tanabe axleback... And I like it! I'll report back after a few runs through the back roads.

Why are you here. Murder that Rc you lucky guy.

If that were me, I'd be M. I. A for the first day speeding, burning rubber and avoiding police.

Report back when you can. Fuel, acceleration, ( vs stock) how the ROOMS react, how fast it revs up.
i wish you only got the tune first then everything after because you are for sure going to see a huge bump with all the performance items you added today.

Ok, I'm here with qualitative results. The car is noticeably faster now, and the 7200 redline is a game changer. In straight line acceleration, the car now pulls as I remember my IS350 did with smooth power up to redline. I did a rough 0-60 using a stopwatch, revving to around 2000rpm for the launch, and the car came in around 5 seconds (as I said, this is not scientific or bulletproof in any way). 5 seconds is a full second off the factory 6 sec mark (4.8 for the 2008 IS350). I live in the hills and have made a few runs through roads I know very well, and yet I felt like I was driving a new car flying into and out of corners faster than what had become routine. So far I am very, very pleased! Unfortunately I am going out of town for two weeks, so the fun is over for now. I am hoping to do some runs at the night drags when I return so I will have some solid numbers to share.

Do you have an android phone? If so, you can try downloading the Torque Pro app along with using an OBD2II Bluetooth adapter to capture your 0-60 times. Not sure how accurate it is compared to using a VBox but it's probably more accurate than using a stopwatch.

and3re

Good point. And its Very accurate. It will record speeds, rpm height, they have 0-60 graphs. All types of graphs on that app.

Any results yet? It's been 3 weeks. What are your thoughts. Any timed speeds?

I spoke with RR racing today and I am really interested in their product. I live in baltimore md so traveling there wouldn’t be a issue for me. I am just nervous with lack of reviews on their product I have a 2017 rc 300. Please tell us more results. Maybe pictures or YouTube videos. Are you local as well?

I still haven't been able to make it to the strip to get any solid numbers. I also tried to get a dyno session, but there are no linked AWD dynos in my area. Using the torque app, with my phone secured in a mount, I was able to get a 0-60 mph in 5.7 seconds, with a calculated 290 whp (take that value with a huge grain of salt). I believe the factory quotes 6.2 for stock. Also: #1 the AWD is surprisingly horrible for launches, I really felt like I never got a good launch as the car always seemed to bog down for a second immediately after I hit the gas (this is likely the center diff transferring power to the front as it detects slipping in the rear, which seems to function even with TRAC off) , #2 I was doing the 0-60 with my heavy 20" wheels on, so the time should improve with the stock 19" wheels, #3 it was a very warm and muggy day.

All launches were done with trac off. Unfortunately the road I use, which can safely test the 0-60, is not long enough to get a 1/4" time. Fall is quickly approaching in Oregon, so soon the car will go back to stock for winter. I will try and do a few more runs when with the stock wheels on, hopefully bringing the 0-60 time down a few more tenths of a second.

Regardless of 0-60 times, the car pulls so much stronger than it did before the tune and exhaust. The combo of the tune, exhaust, coilovers, USRS (from RR as well), and 20" sticky pilot super sports, have turned my car into a very serious machine. My friend who drives an E92 with Dinan mods came away seriously impressed after taking him for a test drive.

I highly recommend getting the RR tune.

anybody know the part # to the RR Racing tune? or do you have to order directly from the website

rcJten

You can order directly from RR, they have great customer service, or there are a few other CL vendors that sell the RR tunes as well.
