need some maintenance advice hey guys i have a 2000 z28, now i bought the car with 70,000, installed longtubes no cats and summitt x pipe with borla mufflers at 82,000 and now my car is at 90,000 currently. i have been driving the car untuned for almost 10,000 miles. i also have been only doing the oil changes every 3-5000 miles. so as of right now besides a full tranny flush and coolant flush and changing the diff fluid what else should i change or take a look at when i put the car on the road next summer? i plan on modding the car some more come next season, so with 90,000 miles what are some things i should be careful of as well? thanks in advance.
Are you running synthetic oil? If so 3-5k miles is not bad between oil changes. Id do a trans flush, coolant flush, and change the rear diff oil. Check the air filter(clean it if its a k&n), replace the pcv valve, clean the mass air sensor, repair any and all leaks(axle, pinion, trans, rear main, front seal), change the plugs if you havent already(NGK TR55s are nice replacements for stock and well priced), maybe change plug wires(I like the MSDs personally)
just sayin def change the wires when you change the plugs, some ppl say it doesnt matter but my car was misfirin like a bitch when i just changed the plugs and not wires, also i would seafoam the car just get any gunk outta there.there was a really good write up somewhere on this site

i have thought about it but i would rather spend my money on a dyno tune so i can get the cats set to ready so my check engine light will go off and i wont fail inspection.

naa it shouldnt have any issues a lot of people go untuned a tune would pobably give u a little more top end and what not but it wont hurt it by not having one. honestly i had my car laptop tuned and i didnt notice much of a difference even after torque management was removed, wot fuel was leaned a bit, and timing was advanced. but it was worth the 125 bucks to get rid of my ses light
i dont know about the Gm stuff, im sure it works just as well, and i seafoamed mine and it didnt make a whole world of difference but def felt a little smooter ride
