I had all my traction assists off. I went back to check and made sure all my hoses related to this mod are on tight.. they were fine so still puzzled how some are claiming increase on all ranges of the rpm. Anyway its a pretty simple mod.. i don't see how i could mess it up.. I'll post pictures some point over the weekend for those who suggessted it.. so you could see if i messed it up or not.
I took delivery of my ordered car with 8 miles on it and ran nothing but premium. The fuse pull woke mine up for sure. even my wife noticed it.
just make sure you pulled both fuses and they were the right number. I thought the fuse pull was BS until I did it. Now some say it does nothing but on my car it was noticable. this was even before mods.
need to get on a dyno or at least datalog the car. right now it is all speculative posts. The butt dyno is not calibrated very well.
to people who say 25hp is not noticable it disagree you should be able to feel 25hp. so if you don't it is either some kind of wied misconception IE the power is just even more linear not and is fooling you or you maf transfer function went off for soem reason and you running rich robbing power.
