Lean at WOT?

My a/f gauge shows me running lean at WOT. Do I need bigger injectors or is there a way to correct this thru programming a chip?

As much as they get in depth... this is the only other board on TGO I frequent...

I've got to get ahold of a SD 3.1 setup, to figure out the prom info - and build a chip to run the turbo setup!

Also, are you doing 15's on teh stock injectors? If so, get some 3.4 injectors - they are 17pph, instead of your 15pph - and will help you out.

I have a set of LT1 19pph's laying around, will they work? Will I need custom programming?
