hi there
i just installed a meth injection kit on my evo 9..
i did 3 dyno runs..
- 1 without meth
- 1 with meth but without touching my tune
- 1 with meth and with a full tune
i'm glad to say that with the 3rd run, i managed to pick up 25whp and 30wtq.
however, what puzzles me is that on my 2nd run, my hp/tq figures actually dropped from the 1st run. my tuner says that this is due to the fact the meth makes the car run richer by 20% as meth is actually extra fuel.
is this suppose to happen normally? i thought i would see gains even just by installing the meth kit w/o a tune.
hope you guys can enlighten me here.. thanks!
