The answer will almost always be yes. I get asked this mostly when small mods are made to a ka or sr, or if they have a stock ka or stock sr.
Today I tuned a ka24de with stock injectors, cp 9:1 pistons and BC 264 cams, an intake, and 3" exhaust with testpipe and header.
He was using 89 pump gas.
The blue line is with stock mapping and the red line is when I was done.
Considering building the engine with cams and pistons (which are lower compression than stock with hopes of turboing some day) and the full exhaust was not cheap the performance gains on the stock tune could not have been much at all.
For around $500~ for the chipping/dyno/tuning it tied everything together.
There is a 30-40 hp gain almost everywhere and around 40 ft/lb of tq everywhere.
