Do you need to be able to switch around your a/f maps to spray? My concern is I have the base model w/out cruise control so I can't switch on the fly?
Can I still spray?

general rule of thumb is to pull 1 or 2 degrees of timing for every 100 you are spraying
did a 100 shot for a while, 1 step colder plugs, stock timing, window switch, wot switch, wideband, kept melting plugs, added meth injection, then it made terrible detonation. pulled the meth off and still had problems, was never lean, a/f were low and was always rich. will a/fs be different depending on what gear you are in? for example, will 5000rpm in first gear have the same a/f as 5000rpm in 4th gear on spray? i think i almost always monitored my a/fs in first, but would spray pretty high. i have an auto too.
i now have no compression in cyl #4, in the process of building a fully bolted NA and will get a professional tune for a 150 shot

Wow, be careful bro, might want to do it all wet, I'd also move the nozzles a little closer to the throttle body too. But either way, that's cool, bet it feels good

it has worked good so far for me so im not gonna change it yet. i have thought about switching the 2nd stage to a 50 wet but i havnt done it yet. and with this new intake the nozzles are both about 2 inches closer than what they were with my old intake.
but yea i drove it lastnight and it felt real good. i cant wait to get it back to the track. maybe i can make that #1 time harder to get.

eh i always did 1-2 per 100 on my camaros and never had a problem, outside of the stock 305 with a performer rpm air gap running a 300 shot through a jacobs mastermind controller(was a 75 shot at 3000 rpms, 300 shot from 5500-6500.) pulled 6 degrees of timing and ran the coldest copper plugs i could find for it melted a piston after about 26 passes down the quarter. was fine once i had it bored and switched the cast pistons for hyper's

so i have a 100 wet on a wot switch right off the line. and then have the 25 dry on a button, that i engage in second gear. just playing it safe. but im still on stock timing. stock tune. just raised the rev limiter to 7200 but i have 1 step colder plugs. i may move it to a 125 wet +25 dry in the future. but its working great for now and i have the fastest nitrous time right now. and i just did a bunch of changes on the car. im hoping to hit 11.5x on a 125 this fall.

i have had it on the dyno and the a/f was around 12.8-13.2 with both shots on.
that was making 360/380 to the wheels on a dynojet, running stock map with rev limiter raised. that was also before longtube headers, ported lower plenum, takeda intake, ported tb.
i will go to the dyno next week one day and redyno it.
