Agreed, w/ an open element filter (that being an aftermarket MAF, K&N FIPK, Steeda CAI, etc...) the headlight out does help. I have proved it MANY times. I've gained as much as a full tenth depending on weather.
Well, here we go, a mod list......
I ran a 13.5 w/ lil traction w/ these mods:
FRPP Headers
Magnaflow O/R X
Flowmaster 1 chamber dumps
4.10's
3000 Stall
Custom Shift Kit
Tranny cooler (doesn't improve ET's, but improves tranny life
)
X2C U/L C/A's
removed front sway bar
Steeda U/D Pulleys
C&L 80mm MAF
FIPK Airtube
BBK 75mm TB
TFS Plenum
JMS Chip
weight reduction
26X10 ET Drags
15X8 Prostars out back...
I coulda actually got a couple more tenths outta it, but the tires were WORN out. I was actually spinning a bit outta the hole, cut a 1.9 at best. shoulda got closer to a 13.2-3 IMO.....
now I've got some 4.30's, a new superchip, plan on getting some aftermarket subframe connectors, and have some new Control Arm bushings to be installed.
Also have a bud who is gonna custom tune my chip, and will be getting some BFG DR's....
Should be in 12's or DAMN close
