If you are having a detonation problem you did the right thing. Pull the chip. JDM should be able to cure that no problem. Pretty common this time of year. A lot of areas switch to a "winter" fuel, which sucks. If you do a line-mod in the trans it would be best to have the chip burned for it. Let the line-mod control your trans line pressure rather than the chip. If your chip is programed for higher pressure and your do the line-mod you do run the risk of damaging the front pump in the trans. It is allways best to let your tuner know exactly what mods you have so he can program accordingly. My .02 |
