    C and L

    You shouldn't need to change your chip. You would only need to if you went to a bigger MAF meter. If you've got all the bolt ons I would go get a custom dyno tune, you'll pick up a good amount of power from it. If you live anywhere near Mooresville, NC you HAVE to go Modular Madness Motorsports...

    Got Dyno Charts For pi swap.

    You should be able to get some really serious numbers with a good tune.

    how much for motor swap??

    I would go with the KB and a really really good tune. If you were talking about a stock headed 2v motor then i would say go with the mach 1 motor. But, with the SVO heads, I think you'd do just fine with the KB. Then, start saving for a rebuild. If you treat the car right and with a good...

    Can I have a gear change without a chip for my auto?

    Yeah, it won't shift right without a chip. Just get a custom tune at the time you get the chip, you'll pick up some power and get your trans shifting hard, fast, and at the right times.

    Wish my Stang was faster

    Just drop a 4v motor in your car, add some good bolt-ons, dynoe tune and BAM! 330+ RWHP. Power problem solved. That is, until a modded LS1/SRT-4/vette, etc..outruns you. The need for speed gets worse the faster you go. Look at me, 03 mach 1 motor, 295 RWHP, and I still think my car is slow!

    Cobra Engine Swap

    I spent $5300 getting my mach 1 motor put in - but that included a custom dyno tune. I'd go with a mach1 motor before a cobra motor(unless it's an 03 corba, of course). The mach motor is alot stronger.

    Do I need a dyno tune?

    You should be fine waiting a few weeks. I went about a month after I did my PI headswap without a tune. Then the motor blew up.

    Chin Spoiler Replacement 96 Gt, Easy???

    If you are reffering to the 03 mach 1 spoiler, then yes it bolts right on. Looks great, too.

    Cobra Heads

    There is a huge compression drop doing this. I think it brings it down to 8.0-8.5. I'm not sure you'd need a new ECU. Many people swap in 4v motors and use their GT computers -just need a custom chip. Cost Vs. performance wise I don't think it's probably worth it. You would probably be happier...

    of the 2 catted pipes which do you think flows better?

    I don't think it really matters what brand you use. I'm making 295 RWHP with a MAC catted h-pipe. And you all say MAC sucks.....ha! Anything is better than stock.

    Automatic Mods

    Right on. Do that and you will fear no 5 spd. Go for 3000-3200 stall. I recommend a Performance Automatic street/strip valve body. Oh, you will need a custom chip to make the converter/valve body combo work well. And don't forget the gears. 3.73s, 3.90s, or 4.10s. 4.10s are probably the best...

    Just got back from the dyno.

    Actually, it's an 03 Mach 1 motor. You'd be hard pressed to get 330 RWTQ out of ported PI heads and cams. At least, you don't see many PI headed/cammed stangs running around with much beyond 290-300 RWHP and 290-305 RWTQ. I think most run around 275-285 HP and around 300 TQ. All I have for...

    Just got back from the dyno.

    About 700 miles. With a good tune you should easily be close to 300 RWHP. I am!!
