Is that possible? My car used to run consistent 14.1's and today it went as high as 14.7's, I finally tuned it a little bit and got a 14.4 out of it. Things I have changed, are, I put a Ram Air II hood on it, new KYB struts and shocks, Jamex 1.5 inch springs, new O2 sensor. Thats about it. I also attempted to adjust the IAC but it wouldn't move, could I have screwed it up somehow and costing me power. I had to adjust my TPS to .60 and timing to 10 degrees before, and bumping the fuel pressure up to get back some of the et. I am running drag radials so the car stays consistent. The new struts, shocks, and springs is the only thing I can see having some affect on my et, but 3 tenths? Mind blowing!

i dont have an answer to your question, but how much did the kyb shocks and struts cost you? did you get the g2 or another series? how long did they take to install? is the ride much better?

 

I got the G2 struts and the gas adjust shocks, bought them from tirerack.com, and the ride is nice but still need subframes to tie everything together.
