My $0.02, malone is pretty good if you have a modern TDI that isnt a weird edgecase or engine swap.
This is just my experience so YMMV, but years ago I bought a stage 0.5 delete tune which did just DPF/EGR delete as I had a DSG but no means to tune it at the time.
About a year passed from then, Malone began having rumors of being able to flash the DSG from a PowerGate3, so I hit them up and they let me a test mule for it. And it worked! From then I had stage 2 for a long long time. About 6 months after buying my stage 2 i believe i bought all my go fast parts, and the accompanying tunes (ECU/TCU). The tunes are "stage 4" but theyre actually custom, they just name it stage 4 to make it coincide with their premade turbo upgrade kits for the CBEA/CJAA.
2 years passed between purchase of tunes and me flashing the damn thing. I had originally set the tune up for turbo + CP3, however i only got the turbo in. With more than a year between the last communication with them, I sent a message to drop the CP3 tuning off the remap so I can get the car running with only the turbo. The next morning I had a new tune right there waiting for me. I flashed it, and we did 5 or 6 log runs/revisions until we got it pretty dialed in on the same day! No more faults/limp mode, car is fast, and boost response is nice.
I have a hardware problem where the turbo vendor didn't set the actuator properely, so my low end boost response is a bit lacking. Sometimes it is as much as 5 PSI off of target!! Regardless, Malone was able to get this all set until I put the rest of my parts in where I told them I will yank the turbo and set the actuator properly.
Now I can't speak to other tuners on the forum, or on the web, but the customer care alone with Malone Tuning is worth it's weight in gold to me. Sure I may not be pushing my hardware to the edge, eeking every last drop of fuel and every last pound of air but the tune is stable, the car is fun, and it gives me a little confidence knowing im not riding my hardware at it's limit.
For what the tune is, I'd say it's good.
This is just my experience with a CJAA motor, I have read some stuff that their older tunes where hit and miss, dirty, etc.
If I pickup another CRTDI, Malone would be the ones to tune it. My parents also have a JSW TDI and I have recommended tuning through malone for them aswell.
I'd also like to point out that you rarely hear about someone having a good experience with big name brand stuff, but you'll certainly never hear the end of it if something goes wrong. I understand we all stick up for the "little guys" individual tuners here on the forum, but they're not having the public exposure these other big name tuners have. I can go into just about any TDI facebook group and see the same smack talk against Kerma, just the same as i see here for Malone. For what each of them do, they're good and I don't think it is a waste of money.
For CRTDI's:
Any plans to delete? Malone
No plans to ever delete? Kerma
