I am thinking about getting a chip to remove the stock rev limiter(getting MSD) and hopefully take care of the fact that I have no smog pump. First off is this possible and second can I get this off the shelf or do i have to get it custom done.
With your set up, your engine is making peak HP around 4600-4800 rpm. There's little reason to rev it above 5000 rpm - let alone going above 6250 rpm. If you do, you're just making noise and putting wear and tear on the engine. You'll go quickest by keeping it in between the torque and HP peaks - which in your case is about 3600-5000 rpm. Why do you want to remove the factory rev limiter? If you're going by the stock tach, they are notoriously inaccurate.
As for removing the air pump - you don't need a chip to correct for any effect caused by it's removal; just take it off, block the crossovers and tube to the cats, and put a shorter serp. belt on it.
If you decide to get a chip (the benefits will be minimal with your mostly stock set up), I wouldn't bother with a mail order unit. I'd only have someone local do it so you can actually drive the car and adjust things according to how it runs/drives.
The reason for removing the limiter is this summer my car is going on the bottle so I want to make sure that there is no chance for the fuel cutting out ie stock rev limiter
My smog pump has been removed as long as I have had the car. I would just like to get rid of the codes the computer is throwing because the pump isn't there.
I live about a half hour away from Paul's High Performance so that is where I would get a custom chip. I just was hoping somebody made a chip that I could pick up cheaper then a whole custom tune. I'm not looking for the performance gains out of it more then anything I just want the safety for when the bottle is on there.
I was going to use a window swotch to assist in turning on the system, can I use the same box to turn it off also or do I need another switch all together
