Lightbulb More power '87 GMC TBI 5.7l

Anybody have any tips for getting more power out of my 87 GMC 5.7L TBI w/o buying a new engine. (let me clarify.... The engine is in great shape, just don't want to buy something bigger.)

Go to this forum and start reading:

If you are willing to learn how tbi works there is a lot of potential to get more power out of them.

TBI engines are usually held back by the ecm programming, so even if you do the usual mods (cam, headers etc) you may not realise their full potential. This is becomming less of an issue with Win ALDL and custom chip burning. Good luck.
