Dry shot tuning question
We have ran dry for a while. I didn't read all you posts. there were others who said switch to wet and it won't work. It will and can. Any type of kit over 200 you should know what your doing or at least your tunner should .Theres alot of bad info out there nd people take it as gospel.
your car is fast just i would try not to come of as the end all be all. we went 8's with our street ls1's on stock computers 4-5 years ago.

I do a lot more reading on here than i do posting.. but I have had a lot of experience with LS1 tuning and dry kits...
When ever you tell some one your running a dry kit all think you do is spray though the MAF and alls good.
or if you really want to make it fast you need a wet kit.. both are not 100% accurate.
Not making exusess.. But a IRS Full body car isn't ever going to the fastet kid on the block,
I did had a 2001 Z28 for a few years but it wasn't until I got the GTO that I was able to get a little more serious..

If so, would you recommend a n20 tune or will maf compensate with my current tune that i believe is 12.8 afr

What about with the 85mm MAF, are these at same risk if any, than the stock Ls1 spraying pre MAF?
Ive been trying to hook up an HSW module and havent been able too. What timing devices is everyone using now?

That mod works but the resistor value advances timing, thats not what you want to do with a nitrous set up.
I have run it like that the track rather than wire in a relay and it worked well. Now I just have my retard worked into the tune.
What about disconnecting the AIT sensor completely, would that retard timing? Also, if only spraying a 36 zex pill which comes out to be like a 35-40 hit. Would this hurt the my engine in any way, given i spray pre maf.
I think if you just disconnected the IAT it would throw a code.
You would likely be okay with a small shot on stock timing but every car is different. I have run a 50 shot on 28' but watching AFR and reading plugs has to be done with any size N2O shot IMO.
Also what size injectors are you running? With the mods in your sig, stock injelpctors may already be max'd out.
Since Pat G. Tuned it, PM him and see what he would advise.

Everyone I've asked about the small shot tells me it shouldnt be a problem... But thats theory, i want to know from those who have actually done it. My Inj, arent max'd out yet and they are the stock 28.8#. Just want to know if pre Maf will really compensate for fuel, since i wont need to retard timing on such a small shot.

Do you have a way to log data with HPT or other tuning software?
With your mods I would bet the 28.8's are max'd. I max'd mine with just bolt ons. Keep in mind that rule of thumb is not to run an inj. past 80% DC.
I currently have 36 lbs inj. and push them past 80% DC on a 100 dry shot. I should go to a 42 or higher but don't want to go through the trouble of turning and scaling injs. again so I am basically taking the chance on running lean but feel confident my tune is dialed in.
Also remember that the stock fuel pump will only support up to about 450 rwhp.
Would you be safe as is with only a 40ish hit, yes likely, but I just want to make you aware of the possible issues and what to look for.
Bottom line is that with any nitrous jetting, logging or monitoring AFR's and having someone with experience read your plugs are the 2 most important ways to ensure a safe nitrous tune.
