so the balance shafts are gone, and I am not seeing the power I should, I have (or close to) super60 turbo, gm s/c trio, FMIC, 2.3 intake, secret cams, NGKTR7's, 310cc, begi 2025, and I run 11.9-12.1 under 9-10psi boost.
I run premium fuel and I can feel the engine misfire under boost, sometime in first/second the engine limps (CEL flashing) takes 10seconds to get going again, then back to normal. Sometimes the light doesn't flash but still limps the same.
3rd-5th runs clean never throughs a code or limps, but you can feel it missing, kinda feels like spark blow out, but I am gapped at 0.030 already so I don't think that is the problem.
is it possible that I am getting knock retard because I removed the balance shafts, and have stiffer mounts? and what should I do to fix this?
2) I also searched about injectors and I have a 2000 with delphi style injectors, I plan on going with HPT within 2 months, which 550-650 cc injectors are cheap that will fit our harness? I can change the harness but I prefer not to have to modify the rail or injectors.

Sounds to me you are blowing out the spark. I had a similar issue and we just kept playing with the gap, or you could be too rich. how do the plugs look?

Why the S/C reflash AND an FMU?
"The FACTS are always subject to CHANGE once the TRUTH is applied"
"In the entire history of man the only stupid questions are the ones that don't get asked"
s/c reflash is for a low cfm "boosted"application, I use the FMU to raise at 3:1 approx to obtain the 12:1 AFR

plugs are a nice brown color, like they should be,

speedracerz ran more psi than that on the s/c reflash
but it sounds like the spark is getting blown out , or ign system issue , or to much fuel
try the plug gap
im running mine around .035
Speedracerz isn't the only one that ran more psi on the reflash without a need for an FMU.
I ran the s/c reflash, 440cc injectors, and an Apex S-AFC to just make sure the injectors didn't make things TOO rich. Never had any issues w/ spark, just the fueling due to the rather large injectors running on a reflash that is meant for 310cc's...
boo boop be boop.
