if lookin to rid excess components, standard answer is hpt is not capable and does not support such a function (as is illegal). As for if you have to buy it in tandem. i am not sure how this is done on the l5p. You need to get a stock file (probably via tis) and it will need to be configured to work with efilive. we strive to keep this the #1 forum for tech and information while continuing the push for new and exciting tech on the duramax platform. From all out performance. i'm on group forums for the delete l5p's but i just don't trust the tuners out there to do the work. That's why i am wanting to try and tackle this, but i want to know. I got the hp tuner with the unlocking device on my 2020 2500 chevy. Hooked everything up and started downloading the 2 tune files i was sent. the sotf tunes weren't cheap, but a proper ecm tune did add significantly more power than the derringer. I suspect the edge evo ht2 is probably the best. with motorops and hp tuners, we can guide you through the l5p and l5d tuning process. Power and fuel economy are waiting! We offer motorops l5p tuning using.
