Good morning everyone! I recently bought a 2000 SS with a few modifications. Long story short, it runs like crap (when it runs). A friend bought an HPI tuner and we are playing around with the tune, but can't get it right. So I had 50lb injectors that we thought could have been the issues because it seemed like it was running rich, so I replaced them with 36lb injectors. It seems to idle "better" but not any where near acceptable. Any suggestions? I can send the current tune to anyone who can help. Thanks.

Modifications: Long Tubes, Torquer 2 Cam, SLP intake, Yank 3800 Stall, 3.73 gears

More to come...

 

No matter what injectors you are using, the first step is to make sure you have COMPLETE (and accurate) injector data for flow rate, offset vs voltage, and short pulse adder. Missing on any of these will have you chasing your tail on everything else later.

 

What 36# injectors did you use?

 

If you’re willing to send a file I can help you out. Pm me for info

 

Minimum injector pulse is often missed. Maybe worth taking a look at that.
