The gains are zero if you're not already having ignition issues.

whats the sr20 setup like? boost fuel management etc

what plug gap?
ive got 87mm cp pistons, h-beam rods, cosworth head gasket, bc stage 2 cams, walbro, 740cc injectors, aeromotive fpr, jwt ecu, 2871 turbo and spark plugs are iridiums gapped at .028.

what psi? that setup doesnt sound like you should have spark blow out problems.

the stock COPs were s13/14?
before the rebuild, it didnt do it. something changed after the rebuild and i dont know what. all new gaskets, new couplings - everything. just made no sense. it runs like a champ now. 20ish lbs of boost. only when driven aggressively would it do it. and only in the 1st 3 gears. after that it smoothed out. now it doesnt do it at all. the stock cops were s13.

i think i might have found a problem with my setup that i would not have seen without the wideband i installed this weekend. im going lean after 4k rpm. i think its shoddy vacuum lines. not that my lines are bad - theyre all brand new braided, copper and rubber lines. just too many on my fpr line. changing that right now.

your stock coils will work fine, havent had issues with mine yet. No need to spend $ where stock will do

update from a couple months ago - the problem turned out to be bad voltage going to the fuel pump. fixed that with an external relay and the lsx coils smoothed it all out. it runs like a raped ape now at 22lbs of boost.

I imagine as long as the coils can handle being supplied with 43KV then that would be some serious voltage arcing across the spark plug.
