Just curious really my 92 z28 is of course a sd tuned car no maf. My question is with a mafless setup will the car recognize when I do bolt ons and air changes like a maf setup or wouldi constantly have to retune it for every mod ? I noticed when I redid my exhaust today that it had a 2 1/4 cat I pipe and flowmaster it always smelled kinda rich and even worse when I cleaned out the cat. Well now its got a new 3in magnaflow cat and 3in magnaflow catback it pulls much smoother and has no fuel smell hardly at all. I haven't checked my timing yetto see where its at the idle is right at 700 and I run 93 octaine non ethenol have no pinging and such. I know my 03 yukon with 5.3 is maf and when I first got it and still ran 87 gas I put a 4in cai on it and the first trip out under wot it pinged and valves chattered but after a few days of normal driving it pulled like a raped ape its been tuned for 93 now and has full boltons but when I did that intake I noticed the biggest pcm compensation.

 

should be no problem yet

 

MAF is much more forgiving to modifications than SD without tuning.
If you plan on doing much more, you should get your hands on a Snap-On Ethos, MT2500, GM Tech2, TunerProRT, or something else that'll stream live data.

I wasn't able to go too far with my SD without tuning. Tuning made a whole world of a difference.
