Don't bother. Go for a JB4 if you want a tuning box
How does the bluespark tuning box compare with a JB4? I realise the JB4 tend to have much more to them than most tuning boxes with the ability to read much more of what's going on. Just wondered if bluespark was similar. I'd generally prefer a custom rolling road map but at least if you go Revo or Apr it's tried and tested.

I had a TDI tuning box on my 1.5 150 tsi, kept getting EML’s so took it off and returned it

Honestly, buy cheap buy twice
Only one worth going for is the JB4

With jb 4 your getting a lot of extra features and also the support of customer sevice reading logs and providing updates and help. Also support from people who use jb4 daily throughout the forum.
For a performance petrol definitely either a proper remap or a JB4 - absolutely thousands of people across the world running them, with a proven track record and lots of support.
Everything I've read about the DTM etc boxes just show over fuelling issues and EML problems galore.

They didn't feature the JB4 unfortunately, as it would've shown it's the next best thing to a remap. Extremely customisable with in depth logging capabilities. Capable of strong power without issues
Also, why would you trust a company who "specialise" in TDI tuning (yet can't get that right) to produce a box for your TSI?

100% this. Anything that spoofs sensor readings but doesn't access the canbus to check what side effects it's causing? That's a hard no from me. JB4 is the only plugin system I'd ever consider - just a shame it doesn't work on diesels otherwise tbh I'd have gone that route
Ran TDi tuning boxes on all of my previous diesel cars and never once had a problem. this included 2 Focus, 1 Mondeo and 1 mazda. To be honest there was always a marked difference when I removed it for servicing etc.
They are alright if you have a warranty you don't want to mess up, but if this is not an issue then yeh remaps are better

Diesel cars are different from modern tsi engines. Tdituning boxes just dump a load of fuel in diesels. Modern tsi engines are more technical.
