limitations of my 98 pcm and a few questions just wondering if i should try and swap to a newer pcm or keep my 98
i plan on building a built 370/408 w/th400 and a 9 inch that one day i hope plan to see 750/800whp as i will be starting with low boost to get all the bugs worked out
now can i use a 2 bar map from a s/c cobalt like everyone seems to be doing?
should i keep the maf or ditch it?
injector size i should shoot for for 800whp? im running twin in take pumps?
any info or guidence to the right direction id really appreciate it

That being said:
Personally, I'm not a fan of the twin in-tank pump setups, but that's just a personal preference. Many people have used them with varying degrees of success. Injector size is going to be a MINIMUM of 60lbs/hr@43psi...probably more like 72lbs/hr@43psi....with a boost referencing regulator and 1/2" fuel line....and a sumped tank. Cobalt map sensor should be fine up to 15psi or so...I would definitely change to a 2000 or newer ECU.
Again, these are just my personal preferences. Ask around here a bit, do some research, and make your own best decision. Hope this helps.
