[QUOTE="heatsoaked12, post: 15677166, member: 127489"] Hello all, looking for help with an issue on my 12 gt500. Since I had a t56 magnum xl trans installed my first gear acceleration always seems to be limited, it feels flat. I went with the 2.66 first instead of the factory 2.97 because I thought first was too steep . I have a feeling the engine control module may be freaking out and pulling throttle because the engine output compared to the transmission output aren't what the ecm is expecting. I'm not sure how to prove whats going on , I just know it wasn't this way before the trans swap. I've tried two different reputable tuners without resolve. Does anyone here know what I can do to make my car run as though it were throttle by cable? just for testing ,could I pull my speed sensor and still get wot without the ecm shutting everything down? I have no codes at all, just first gear take off lazyness. Once i shift to second the car pulls very hard. Thanks in advance for any help or interest. [/QUOTE]
