Post a wanted advert. Stock injector chips are about Free.
You have to use a scott simpson Thrasher for it to work with the stock 233 FP regulator. Regular thrashers are set up to run with the TTA/FWD regal 237 FP regulator. The thrasher has open loop idle and will very likely not pass emisions. Scott can burn you an emissions chip for $15.
Even if the car is all stock, it is a VERY GOOD IDEA to replace the fuel pump with an aftermarket Walbro. Ramcharchers is having a May special for $89 you get a Walbro 340, which is a killer deal. It may be more pump than you ever need, but it is better to be safe than sorry.
A weak stock fuel pump can crap out in the high 14's. My car wouldn't run a 13 until I replaced the fuel pump.
