Hello forum members, around a month ago i purchased and the lap3 protuner for my 2020 veloster n pp. at the time of the install the car had around 11,700 miles on it, was completely stock, and had no issues. I had an experience and licensed car technician ( the person actually worked on the show pimp my ride, fun fact) who installed it. Upon the initial install and startup the car ran very rough, had no tach reading, and tons of warning codes. turning the car off and back on again yielded no solution. I was able to find out it was the p0335 sensor through a scan tool and after I simply unplugged and plugged the crank sensor back in it worked flawless and the power gains were noticeable (and quite awesome). last week the same issue came up again. same code, etc. I turned my car off, jiggled the connection (barely) and wallah the car was back to normal. Upon speaking with David Chung about the issue he believed that during the install part of the harness was broke. Beyond the initial install it had been working fine up until this point and besides the tuner, the car was completely stock. Today the third issue occurred. While I was driving on the interstate i was WOT in fourth and the turbo just stopped working, no noises, no stuttering, no dash lights, it instantly lost a ton of power and the turbo reading just read 2psi despite being the full throttle. I got home, turned it off, waited for a few minutes, turned it back on and it works like normal. I was just wondering if I could get some advice as to what i should do from here, does a return then exchange of the unit and/or harness seem like the only option or can the issue be something else? Thank you for reading this and have a good day.


btw i have the csv log of the incident i am just not sure how to convert it and put it in a file that is small enough

I'd have the entire unit exchanged before the warranty expires and take it off the VN in the meantime. You run the risk of engine damage with a faulty unit rather it be harness or module.

I voiced my informed opinion with regards to the Lap3 Pross tuner months ago. Sometimes, this has to happen for purchasers realize the unit isn't well made or worth the extra expense. Personally, David Chung needed to immediately replace the unit or make you whole by refunding the entire amount. He's not done this obviously, which is a pretty good indicator as to their customer service.

Personally and with good cause, I believe they're junk and the support you receive, (as I mentioned long before) is non-existent. It pays to do the research beforehand, so you don't have to go thru this type of issue. "Caveat emptor!"lain:

If I were you, I'd send it and ask for a complete refund.
