You can put a cam in it but a tiny one. But you can get chips from jet performance if you want to mess with it not worth it in my opinion best thing ive found to wake up a TBI is crank up the fuel pressure.
yes but how do you do that. a tech friend of mine told me the TBI 454s were real bad about running lean. he's telling me to convert it to carb..... but wont that set check engines lights from hell?
Get an adjustable fpr and put it in the line behind the tb. Do a search on tbi and there is some good info out there.
fullsizechevy.com has a TBI perf section. check that out
You have to get a prom that replaces the one in your current pcm. Give Arizona Speed and Marine a call. There's a guy there, I think his name is Mr. Brown. He will certainly help you out a ton.
