Unsure how this happened.
After installing kooks LTs, catted X-pipe, this GT500 is down on HP in a big way.
Mod list:
jLT 127mm
Frpp twin 65mm TB
TVS blower with 2.4 pulley
Afco HE
170 stat
Kooks LTs
kooks catted X pipe
Stock axlebacks
New tr6 plugs
After installing the LTs, x pipe and HE I saw some serious timing being pulled and it turned out to be a bad IC pump. That's now been corrected but the car made 688rwhp prior to the LTs and yet it feels and runs like a 120mph 580 rwhp car.
Just got run down by a 125 mph car.
I even reloaded the tune from the pre-LT days and it's unchanged.
Any thoughts on what could be causing this?
