SSTT to Dinan review.

I got my 08 Step 335 coupe dinan flashed a few days ago at Dinan-Campbell here in the South Bay. Pretty much every review has been right on- decreased throttle sensitivity, more engine drone at cruise, and an overall smoothness that was lacking at stock levels. Instead of boring you with all that, heres the performance differences.

The SSTT was a nice little bump in power over stock that was trouble free. Part throttle response was improved and power in all gears was evident right away and more with further adaptation. Even the jerkiness at take off was less prominent with the turbo tuner. I added the BMC air filter and the car felt even better. On a 100 octane mix with our crappola 91 octane, I reeled off a 4.66 0-60, 10.9 0-100 and 13.09 at 109.4mph on my g-tech pro in sub 50 degree temps at a soft 1100 rpm launch and 1/4 tank of gas. Not bad.

Why upgrade the SSTT to Dinan? Simple. I would always have to fill up with 100 octane at my local 76 to really feel the turbo tuner come alive, torque and powerwise. It started to be pretty bank for me even tho fricken 91 here is almost 4 bucks. I also wanted more low and midrange torque that the Dinan dyno curves have been showing and a little more from 5-6k rpms.

Now to the Dinan: adaptation was pretty quick with a few wot pulls. Prior to the flash, I filled up with a full tank of 91 and stock air filter to see how that compared on the butt dyno to the SSTT with 100/91 mix. The torque from 3k to 6k is amazing and very addicting. This car now has a very linear power burst up the rev band. Highway pulls are more fuller from 4k to 6k and just ramps up without a let down. I cant wait to fill up on 100 octane next week and hopefully make some real passes at Infineon with a couple buddies- wish I could run at Sac tho. So for fun, last night I did a couple g-tech runs in 54 degree night. 0-60 in 4.39 0-100 in 10.2 and 1/4 mile---12.90 at 111.8mph just flooring it from a dead stop with no wheelspin. Then I turned around and immediately ran again but with a 1500 rpm launch. I got 4.61 and 13.05 at 109 with major chirpage of the tires. Maybe heat soak, definitely felt slower the second time. This was with the bmc filter on btw.

All in all, I am happy with the Dinan flash and am waiting for stage 2 since the power does drop after 6k. Both the sstt and dinan are great upgrades over stock. Different strokes for different folks..

Nice review, good to see some numbers. Dinan is making a killing off these flashes.

Well on 91 octane, the Dinan definitely feels a bit better from 3.5k to 6k compared to the SSTT on higher octane. 91 to 91 is a big difference torque and power wise. I havent tried the Dinan yet on higher octane but would only guess that it is fairly better due to higher boost and the dynos showing about 50whp and 70wtq. Bang for the buck, its your money so I cant say, but I was able to sell the turbo tuner same day.

Thank you for the review. Like Bubbles said, there seem to be more and more happy Dinan customers. Good to see you enjoyed the SSTT as well.

Good review and comparison. Enjoy your new tune.

MargNg335, Since your'e in the bay, we can do a roll on run if that'll help you decide. To me, the SSTT was a nice stop gap, while the Dinan is a true tune of the ecu that does so much more than raise boost. So many parameters are re-mapped. If you've driven in a reflashed car-I had Ecutek with supporting mods on my previous WRX and my current LegacyGT daily driver, you can appreciate the flash.

A SSTT on a two year lease car costs approx. $150.00 ($600 - $450 resale) or about 20 cents per day. You can't beat that!

Round 2

Let's try this again and start from the top.

Does the flash feel that more powerful than the SSTT or about the same?

So the use of "both" products provides an "accurate" opinion?

Seems simple, just keep it on topic. Too bad it is impossible with all the competing "fans".

This is nothing new, time will pass and as more people get their tune of choice I suspect there be less problems.

Agreed, just trying to help a member who forgot his opinion on the subject.

Thanks for the input. I'm happy with the SSTT right now, but the Dinan flash keeps popping in my head. I know the numbers are fairly similar, so I was always wondering what "differences" I would actually see by plunking down the extra money. Great review.

I really think that the SSTT owner and Dinan owner are very similar in that they want good, safe performance without having to get into the ecu and unplug wires. There are other options out there that will make more power. This post was designed to let people who are on the fence with the two know that the Dinan has better power under the curve and the driving feel of the two is substantially different. Saying that, I do miss the part throttle responsive that the turbo tuner offered.
