GM “White” 42lb injector issues
GM “White” 42lb injector issues I need some advice/help. I installed H/C in my 99 FRC a month ago. To be safe I also installed a Walbro 255, new filter and Bosch white 36lb injectors (42lb at 58psi). My tuner is having issues tuning for these injectors. Car is pouring fuel into the cylinders at idle. Fouled out all 8 plugs with just 30 minutes of run time (wet when pulled). Any help will be much appreciated!

they're probably junk china knock off. I bought a set of bosch "green giant " even had the model number stamped on the one side. But the guy that did my dyno tune had issues with mine. According to him "They would leak by even when he forced them closed". I spend 300 on the FAST white 36lb and immediately I could notice the difference just the way the car idle. Also when I tuned for the idle there was a huge difference tuning seemed much easier getting a good steady idle. $60 compared to $300 lol

Ditching those injectors in the best thing to do, I don't think it is the injector data that is your issue. I don't know if you have HPt but the data can be found... on here even. And swapping the injectors is easy. The data i found off here worked great for me
I have purchased 6 sets of the white gtp injectors from ebay, installed and tuned my self. You just need to make sure they are authentic gm and not new knock offs like stated.

If they are ebay junk, throw them away. I can show you pics a windowed block and a BTR cam with 15 min on it on why NOT to buy ebay injectors.
If you want to use the whites, Get some from a reputable place.
I use them in a few cars in excess of 500rwhp and still only at 75% DC.
I get mine from 3.8SC cars from pull a part, clean them and get a rebuild kit off ebay for $12.
Also there's a member on her that does the same and sells them on here. Haven't heard any bad complaints about him. Keep checking classifieds

42 is more than sufficient in a NA LS1 making up to 500 whp in my experience
