I ran on Fri night...with a nasty 2 degree temp/dew point spread... the track was nice and dewy...so on my 1st run...i ran 13.9 at 106...couldnt get any traction...even with Nittos...
the 2nd try...i did a nice long burnout...heated the tires nicely...and had a decent start...but experienced the sudden loss of power into 2nd...loss of boost...BUT I HAD IT UNPLUGGED!!!
or so i thought...i unplugged the large power connector under the saucer looking deal to the right of the blower on the firewall...

i have a JDM flip chip...2# lower...nittos...and a LFC filter kit...
any ideas???
over-rev?
over-boost?
im stumped...

 

I think you hit the Rev-limiter, If you have the Boost Unplugged there is no way for it to bypass under WOT.

 

Sounds like you disconnected your EGR valve.

 

Here is the plug just to make sure...
