looking fo more horse power
I have a 98 blazer 4x4 . Ive removed the baffle in the throttle body and the screen in the maf sensor. Ive also put on a k&n cold air intake and high flow magnaflow cat, dynomax muffler....sounds great. Have i missed anything that i can do for a small price?

Considering the first two didn't do anything to help your performance... (I have done the throttle body "mod" and I expand on both of these in other threads so I won't do it here)
The next step I would suggest is a PCM tune (PCMforLess or Wait4Me).

Here is one such thread:
Restrictor plate/MAF screen. Removed?
It doesn't get as in depth as I know I have gotten in the past on these subjects, but you get the gist of it. I have also tested stock MAF sensors without the screen before and their readings are MUCH more erratic than the stock screened MAF. And any restriction that may result from the screen being there could not be measured with vacuum gauges on either side of the MAF sensor for either case.

You won't see that kind of increase from putting on a sensor. It just isn't going to happen. On a highly modified engine where you have a lot higher airflow demands, maybe, but the cam in these engines just isn't tuned to running at high RPM.
Like I said, there are better things to spend your money on, a PCM tune being one of them.

That depends on your budget and experience. The next thing would be headers.
After that, cam swap.
Then there is head port & polish. While the heads are off, have screw in studs put in so you can use higher ratio, aftermarket rockers.
A PCM tune should be done to take full advantage of the mods. The cam swap will likely require a PCM tune anyway just to get the truck to run properly without popping codes.
