Fabo Posted March 28, 2022 Share Posted March 28, 2022 (edited) Hello. I'm new to the platform. I few years back I read some comments written by Mackpro on the topic of upgrading up to a 460hp. Unfortunately I can't find this info anymore. Im dealing with a 1998 CH vin: 1M1AA12Y5WW093579. The 11GBA - 80430. I'm almost done changing out the unit pumps, turbo, and the injector tips. I'm waiting on dealership to tell me what position I need to offset the key way (red or white). My question is do I have to do the software upgrade through the dealership or may I just buy a computer from a 460hp rated truck? And if so, would it be the engine ecm or the VECU or both. Thank you for your time and knowledge.

Mackpro Posted March 28, 2022 Share Posted March 28, 2022 Yours is a 330/350 Hp with the straight keyway. You need the off set keyway , off set right white showing. The software change is only in the engine ecm. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69446-e7-etech-horsepower-upgrade/#findComment-493553 Share on other sites More sharing options...
