coop661 Posted October 7, 2023 Share Posted October 7, 2023 Hi everbody, long time listener first time caller. I recently picked up a 93 CH613. It has a 350 with Vmac1 and a 9speed Eaton. I'm using it to haul logs and it has done surprisingly well hauling 80k. That being said I would definitely like to get a little more power out of the motor. I see these tuner programmer things that claim 10-30% power increase, has anybody on here used one without upgrading turbo or injectors? I'd definitely like to get 400-425 but not if that means great risk of engine failure. Thanks for any advice y'all can give Quote Link to comment Share on other sites More sharing options...
JoeH Posted October 8, 2023 Share Posted October 8, 2023 The E7 was made with a 460hp option, so there's no reason you shouldn't be able to hit 400+, just need the pros to chime in with what your 350 needs to turn it up. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted October 9, 2023 Share Posted October 9, 2023 He has a Vmac-II truck, I wonder if it requires an offset cam key, like the early E-Tech's did, along with a turbo, and nozzles and programming.. I have never done that to an E-7, just E-Tech's.. Quote Link to comment Share on other sites More sharing options...
880joe Posted October 9, 2023 Share Posted October 9, 2023 I believe it was Brett on that was running a turned up e7 running a blixton tuner then went to a full mechanical pump maybe he will chime in before long Quote Link to comment Share on other sites More sharing options...
