GM/Bosch V6 S/C Injector table or info needed. I posted this on HPTs board, but no answers. So...
I decided to try some speed density on the Maggie yesterday and it's running rich according the LTFTs and STFTs compared to running with the MAF. I know the VE is not accurate for me. I think the MAF is probably really whacked out too. I just doubt the stock VE is that horribly off. I'm getting -5 to -8 LTFTs and STFTs are anyway from -1 to -3 averaged. max values are -11 -12.
With the LTFTs diabled the STFTs were well into the teens averaged.
So my questions is does anyone know for sure what the whitish S/C V6 injectors are rated at? Bosch P/N 0 280 155 811. GM P/N 24508208. I've read anything from 38-42 (Google and LS1tech). I hope someone has an IFR table, or just as good if someone knows for sure they're XXlbs at 4bar.
In the stock tune it has them at 37.89 lbs/hr @ 0 VAC. I think they might be 40-42 if my trims are so negative. But who knows...
Any info would be appreciated

Do you mean the white GTP injectors?? Your Bosch PN isn't the same as mine ??
I run the GTP injectors and spent alot of time trying to find definitive values - no luck. There are all kinds of values out there!
RedHardSupra (Marcin) found a Bosch Motorsport Tech pdf during his search for info- on these injectors.
They are Bosch P/N 0 280 155 868.
GM Part #24508208

This injector crosses to Delphi FJ10300 and is shown
as a fit to the Buick Park Avenue Ultra, Pontiac
Bonneville & Gran Prix et al, L67 motor. No mention
of these being the supercharged versions.

Oh, well I thought the supercharged engines had larger injectors than the regular V6. Yes they're the white ones. Those are the exact numbers off my injectors. They are the ones LPE used. I'm guessing Bosch changed P/Ns so one probably replaces the other. The GM P/N is the same so they are probably the same injector (I hope). It's just if the GM P/N is the same then logic would say it's probably the same injector. Yes, this helps a lot Joel. It'll save me a lot of time and gas. I just have to set my units as metric and I'm done.
