Ok i have a hypertech thermorunner chip and a 2.2inch */C pulley right now on my 92 SSEI, everything else is stock. After i put the chip in there was a difference and no problems, now after the pulley it bogs down in 3rd gear, is that because of my restrictive exhaust and intake? Someone told me i should get bigger injectors, and if i do need to how much are they and where do i get them? Oh and the intake and exhaust should be done by mid next week.

I had a similar experience. The exhaust will help you out a lot here, I think. What kind of plugs are you running?

AC delco platinum i believe.

Lose the platinum, and go back to copper. At least one, possibly 2 heatranges colder.

Don't change injectors until you put a scantool on the car to verify that it'* running lean. With my mods, the stock injectors are keeping up fine.
