Anyone got advice on some cheap power adders or mods for a 1994 gmc yukon sle with the stock 5.7l tbi V8

throttle body spacers in my experience are useless not saying for someone else they didnt do anything.

but the best way ive found for some extra power out of a 350 is exhaust, headers, and cold air intake.

and just like CleanSierra said about the vette servo it actually does alot to help to. I just had a vette servo and shift kit installed on my 5.3 and its amazing the difference than before.

99 Gmc sierra extended cab
