terry 336 Posted October 11, 2018 Company that I work for just bought a 2008 Ch, has a MP 8 engine, on the engine tag it says 425E, right below that it says 338 Hp at 2100 is this only a 338 Hp engine, and does it take much to increase the ponies? terry Quote Share this post Link to post Share on other sites
41chevy 9,428 Posted October 12, 2018 Maybe a reflash or a piggy back module for the ECM. It controls the injector/pump assemblies for pressure and squirt duration and I believe the variable turbo gate.- Other than that I'm at a loss. God I like my old units more every day! 1 Quote Share this post Link to post Share on other sites

jkruss82 9 Posted October 12, 2018 Its a 425HP engine. 338 may be the hp at 2100 RPM, but max hp is around 1600-1700 RPM. 1 Quote Share this post Link to post Share on other sites
bts-4120 23 Posted October 15, 2018 I figured the 338 would be kilowats and not hp Quote Share this post Link to post Share on other sites
