I’ve been doing a lot of reading about tuning and data logging but it’s hard to answer specific questions and it seems people opinions vary quite a bit so i have a couple questions i’m looking for feedback on.
I have 91 K2500 with a 350 and 4l80e. I am considering going down the rabbit hole of tuning with a flash chip or something and tuner pro. Questions-
As of now it’s pretty stock. I built the engine last year has about 6k miles on it. Has some small stuff done to it
-Stock crappy swirl port heads but they’ve been ported a little
-rebuilt tbi with injector spacer i believe it had some porting done to it and i just have an open air filter
-it has a better crank than stock from different 350 doubt that means anything
-full exhaust. stainless headers, 3 inch pipe, good muffler, no cats.
trans is under 15k with a shift kit in it.
First question. How much if any would tuning benefit me at this stage? with having no cats and a good exhaust i imagine tuning would at least slightly improve it?
Even if a tune won’t help much now i want to put a cam in and get an adapter plate so i can put a better intake and maybe heads, i have a couple options for that.
Second question, can i do anything transmission wise with the tuning software? Shift points, line pressure lockup etc?
Third. I’m still a little fuzzy even reading thru threads here about tuning. I know i’ll need a cable and tuner pro but what about the ecm side. Something about replacing the prom with a flash chip or?
Thanks for any help guys
