Has anyone used the Racechip or Gan Tuning box on their car. Seems legit and easy to remove if needed but I’ve heard mixed reviews; although most jBe been good. I have seen some posts though that day they the safety features in the engine will render the box useless over time.

Been driving with the bluespark for a while now. Has made a huge difference, then added a pierburg valve in the wg side and it's just all around better and more consistent. Honestly traction is my biggest issue at this point. With my lightweight wheels I cannot floor it anymore and not spin the tires even in 2nd gear... so once these burn off I will be looking for some better rubber.

The "boost" boxes will never be better than an actual "good" tune. Coming from the Evo world I have spent countless hours on a dyno and road tuning my '06 Evo IX. I have tuned and been tuned on 91 oct, 100 oct and E-85.
Fast forward to my N-line. Nowadays dealers are on to tuned vehicles. I will not invest into an additional ECU to have it available to swap out in the event I need to. Plus the cost of having someone tune it that puts the cost over 1K which is not in the cards for me. For anyone else who wants this then great.....enjoy.
The piggyback serves its purpose fine to me. Heck in the early days guys would just use a manual boost controller and step up boost that way. Now the piggyback senses and does this. If you run one with precautions you will be fine. I changed to the recommended plugs and run over 91 oct if I go to Sport+ or Race settings. I will upgrade the wastegate solenoid as all have mentioned as the stocker starts stuttering and is inconsistent. I intend on getting a boost gauge and start doing some logging as well.
Since I only paid $250 for my scorcher and $277 for my Takata stg 2 intake I am happy with the performance/fun factor. Can't see getting anymore performance since N-line is just FWD and a single tire fryer.
So does the Bluespark have 4 settings too? Scorcher has Stock, Sport, Sport+ and Race. I assume A,B,C and D may correlate to about the same on the Bluespark.

So, after running the Bluespark for a few days I'll highlight my pros and cons for this part. I will use the SXTH Element stage 0 tune as a reference point since that's what I had on my Veloster for years.

Cons: This is just tricking the ECU into producing more boost. You still have the funky tune from the factory except now when the boost comes on its much more aggressive. Up against the SXTH tune it is inferior in the sense that on the proper tune my Veloster would jump to 21 pounds of boost from 2,500 damn near to redline. This just produces more boost on the factory tune. SXTH was power on tap, this still has a bit of lag on it.

Pros: This is a marked improvement over stock. If you keep your shifts up in the rev band you stay in boost much better vs stock. It will chirp second gear if you get on it and it pulls much harder than stock. Passing power in 6th gear on the highway, 4th gear pulls like a beast on the highway. If I had to put a number on it I would say this is 2/3rds of the joy from the SXTH Stage 0 tune at half the price. Install was 10 minutes since I don't have a stock airbox to remove.

I'm still on the recommended "C" setting that it came set to. Once I do plugs, packs, downpipe etc. I'm thinking of moving it to D and see how the car performs.

Is anybody on here running it on the D setting? If so could you list your mods and what your impression is vs the C setting?

I ran an E30 tune in my Fiesta ST. The FiST only has a 12 gallon tank so I would add about 3 gallons of E-85 per empty tank. I used a calculator app for in between fill ups. On our tank which is 14 gallons I would figure 4 gallons would bump you up to at least 93 oct equivalent. Here is a link to a calculator:
Have used E85 on all my boosted cars. My Evo made 450 whp with it.

Yes I did and I have checked up on it. Having owned a modded Fiesta ST and Evo I understand the precautions. Was able to get over there and read all the posts. Allot of info there like you said. Thanks for the heads up. Only have 500 miles on it and just enjoy being in sport mode for now running on 91 oct. Didn't think I would be able to find something as reasonably priced and fun as a Fiesta ST but I think I have. Both have their high points but ESGT N-line is more reasonable to live with day to day. Also being DCT my wife can drive it.

Installed my scorcher module this week and really like the response it has given the car. I picked up a used one for $200 less. Installed with it a Takeda stage 2 CAI. It provided the slight induction noise I was looking for and now can hear the turbo spool. Swapped out plugs for the colder recommended set and went through the different module programs. Race mode gets with it pretty good! Just going to leave it in sport mode as it provides a good response until I get about 600 more miles on it and do a oil change. Want to do some 1/4 mile runs as I have seen others get into the low 14's with a similar DCT set up. Coming from a Fiesta ST this is impressive.

Got my bluespark module today. Car never felt like boost regulated properly stock and with this it made it feel worse. Yeah I get how from a butt dyno it could make it seem faster but this is certainly not the way to properly improve your vehicles performance and it definitely isn't capable of making the gains it claims. I'll be sending it back first thing tomorrow morning.

I'm just going back to my original path which was intercooler, downpipe and ecu tune from SXTH Element.

Thanks for posting th
Got my blue spark and installed it today. What a difference! It smoothes out the boost and overall performance. I have the automatic and it spins the tires through 3d gear. If anyone is in the market for one, here's an attached coupon for ten percent off
Thanks for posting that, I used it! Hoping to smooth stuff out, similar to how my Cobb smoothed out my WRX back in the day.

Man lemme tell ya. The bluespark is the real deal. This is my first car that I've ever tuned, but the power/torque gains were so immediately noticeable. Honestly completely changed the car. Looking into what it'll take for me to be able to run the highest setting (E9)

Happy to answer any questions for anyone who has them

So I got the ‘18 Elantra gt base 2.0 model... which blue spark should I order then? Sites kinda confusing
