An aftermarket MAF is a mistake, would go so far as to call it dangerous with nitrous.
On a shift kit Transgo is the ONLY right choice.
If "programmer" is Hypertech then again garbage.

After the headers I would look at gears or a stall, roller rockers and matching springs would be OK but you are far from ready for a cam.

I do not kow where the TR4 sparkplug recommendation came from earlier, if there is such a plug it would be HOTTER than stock, point being watch who you take information from. For every 1 guy who knows what he is doing there are several kids without a clue who mean well but will lead you down a bad path.

That was my bad, a miss type, i just caught it, I meant TR-6's, which I would assume if I am talking about nitrous safety equipment you would just clarify it for me.....

I never used anything other then a Stock GM MAF, especially when tuning, it can throw off the info the tuner puts in and can damage the car. If you tell them you have one they can work around it.

As for the TB all you need to do is follow the directions if they require the slotting of the TPS sensor to retain the same Voltage at idle, and swap the sensors over.

Springs are required to ensure long life. Some people have put them on with out issue but they are the minority, rather then the majority.

unless the car was converted, its a ODB1 pcm.

id go here, speak to Andrew, a really nice guy and a great FAQ section on the pcm/connector thing....

http://www.akmcables.com

The headers should be removed anyways, then you have a lot of room, a air compressor and appropriate fitting should be more then enough. Make sure both valves are closed so the valves wont drop in.

As for emissions, its primairly for weight, the EGR shuts off at WOT, Also it makes it easier to work on the car, so there is an advantage

So what happens if i just take it all off and do the block off plates? Does it hurt anything, and will i have to do anything else so it dont throw codes. What do you think i should do buy the headers with the egr **** or buy the race headers and then do away with the egr stuff?
