Issues with MKM Customs/Sinister Diesel
Hi there all,
Let me start by saying I am new here and if this is the wrong place to put this please let me know. Thanks Mods!
I have an issue here and want some other folks input if I can. Back in March 7th of this year I purchased an SCT X3 from MKM Customs a.k.a. Sinister Diesel with 3 custom tunes for my '03 PSD. I live in California about 100 miles from their location so I had the unit in my hands the following day and immediately read the strategy from my truck and ordered the new tunes. During the order process I stated that I had oversized tires and SCT had told me that I can not adjust that with the flash device so the tuning company must compensate for that. Mike there at MKM said that would not be a problem and I should have my tunes in 3 business days. That was March 8th.
On March 13th so I was a happy camper and loaded up the performance tune. The tune made a nice difference I am am reasonably happy with the performance. But then I noticed the speedo seemed to be off so I checked it against my Navi and my phone GPS and when the speedo reads 65MPH I am actually doing 71MPH so I instantly send an email and call Mike and left a message. I have since called 5 times and spoke to Mike a few of those times and I have been getting the run around about how busy they are over there and he will get to it, I am the first on the list and they are sorry.
Today as I type this it is nearly 9PM my time on March 27th, or 20 days after the order. How hard is it to change the speedo parameter? Should I be requesting a partial refund for the unfinished tunes and go with another tuner? The biggest reason I bought a tuner was to correct the speedo. How long is too long? Has anyone here had issues with this company? It is sad that they are jerking me around because I had planed on spending a lot more money with them for EGR delete and bullet proofing this PSD but I am certainly not going to now!
Sorry for the long post and thank you all for your advice!
