Tuning a 418 in a 1998 firebird So guys thanks for the help before hand but let me get into what I am planning on doing...
ok, so first things first, 1998 firebird that has the bastard computer, can I tune this motor that I expect to make 500+ whp with it or do I need to swap to a 0411?
if i do swap, ik repining is the usual method, but could I replace the engine harnness with a 99-02 harness.
also if i can swap harnesses can I use a harness from a 60e car?
for 500+ wheel what maf do I need? ls3 card style? should I use a 85mm? Does the 0411 or 98' computer even have adequate range? If i keep the 98 computer could i use the 2 bar os and tune the vehicle SD
Last question for now, Injectors, can I use the FF injector from like a 2010 truck for additional capacity, part #12609749, 50lb at 58.5psi.
thanks in advance guys.

i have a 408 that i expect to make around 500-550 rwhp with. Im using the 0411 and have Lingenfelter 100mm MAF.
not sure about the 98 pcm....
im using the FAST 36 lbs injectors (42lbs @58psi)
There isnt a hp limit on a 98 computer. The 98 just doesnt have the resolution and as many tables as a 99+. You can a 1,000hp with a 98 pcm, its just not as fun to tune a 99. You could a 85mm, ls3 maf, or go SD, just personal preference.
