I have my little grey STI 'Limited' with the SPT 'power package' ( )which came like this straight from the dealer. Okay so I have NO clue how quick/fast a stock STI should be COMPARED (I DID use search!!) to one with SPT as there only mods so far. Here is my $36,000 question (which would pay for the car). After breaking in the motor properly, how fast/quick was your stock STI? Then after you had JUST the SPT mods done (and yes it does occur to me that I am the ONLY one who has fallen for the added '45 bhp bump' (@ crank). Did you notice any faster times OR better acceleration OR just a different exhaust note/look and CAI with a nice heat shield? I still find it hard to believe that my 06 WRX wagon 'limited' 5-speed (cause I wanted leather) was SOO much quicker/faster after only 500 miles then this STI with SPT. If by the time I get 2000 miles and my second oil change I can not loosen up this puppy somewhat then the 'For sale' sign will be hanging in its window. Keep in mind that I will not beat on the car before its broken in (in a GOOD way!) I just want some good top end and good off the line punch like the WRX wagon had. Thank you for your support!
