Multi stages, when are they needed?
As far as good 60ft times with an IRS, I've been 1.43 and that was on the bone stock IRS.
I used to not like progressives either until I started using one and now I can't live without it.
I'll probably go ahead and use the 2nd stage just see what it will do to my times.
I still need to figure out what the timing needs to be set at, I guees I'll inch it up until the plugs don't like it.

You should be taking more out not putting it in. the is ALOT more power in it by leaning it out then by adding timing. TRUST ME.
99% of people hurt there nitrous motors by having it to rich then to lean.
If it was my car I would start with 12* of timing and take a 1/4lb of fuel out at a time until the plugs come out looking new or the car slows down. It will slow down before you hurt it as long as you dont have to much timing in it.
My A/F is around 12.5 for the 28 jets.
Thanks, I have a heads up race Friday that I'll have a chance to play with.
I appreciate you guys giving me some tips today.
If I can go faster than a 9.67 it'll be a new GTO IRS world record.

Doesnt sound like the tune up is to far off.
Take some timing out first and see if it slows down, if it doesnt leave it out and start leaning it out 1/4 lb at a time. Keep checking the plugs and good luck at the race !
Hope to see you posting up a new record.

Chris, are you reading the plugs with a lighted magnifier to see where the fuel ring is at? If you arent doing this all you are doing is guessing. I should be out there sat and will stop by.
I think I have my launch figured out now, I just need to stretch out my ramp on the nirous alot more so I can leave with a little nitrous off the line.
I'm sure I'll get my *** handed to me but it should be fun.
I plan on making my qualifying passes Friday and then coming out for the last qualifying round Saturday at 6.
No, I haven't used a magnifyer yet. ( I have one) the plugs have looked really good. The heat spot is right on the bend of the electrode and color is pretty good too.

What plugs are you using?
Thanks. You know a thing or two yourself! 
I was always impressed with your old dry shot heads cam deal back in the day. I was going to do that and then i sold the car. I have another car now but i am on the darkside now. It will be a 402 LS2 with a 101mm. Maybe i will be able to keep up with Chris?

Also get a new set of plugs if you dont have some already and shut if off and the end of the track if you want to get an accurate reading. I think we can get a 30 or 40 out of it anyway.
That's how I usually check the plugs.
I've been running 9 NGK's but I ordered some 10's today.
I'm still a little on the fence about running a 2nd stage but I guess I'll wire it up tonight.
I'm thinking I can get at least a 50 out of it.
