I agree to upgrade the tranny first and then consider to put bigger injectors in. My new 129% nozzles brings 90HP and 225 RWTQ with the stock tune. With some aftermarket tunes you can expect much more on output. See my dyno chart from the nozzle testing with stock tune, mod intake and exhaust like you have, beside an upgraded tranny.sinaloa;1564102; said:would getting 100hp injectors make a big difference on my truck?? i currently have edge, intake, and exhaust.
