safe to run super rich?
safe to run super rich? Just got new motor in car, changed alot of airflow characteristics ie headers ls6 intake x3 cam etc etc, so i upgraded from 26lb injectors to 38lb. I am now running so pig rich the car reeks of gas when it runs and is smoking, which smells like unburned fuel. I have to drive 2 hours to get this thing tuned, am I going to ruin my plugs / anything else doing this? I beleive this is a tuning issue only ( i hope ) any insight into this? I have iridium tr55ks and you all know how changing the back plugs are so Id like to avoid if possible, but a local tune is 800+ and i can goto little rock and get an EFI LIVE/wideband WOT and drive tune for under 300.
Well, first remember that you get what you pay for and the local guy is always my preference of tuner (unless they suck or don't know what they are doing)
Running overly rich can damage the motor...
I would put your stock injectors back in the car and drive with them to your tuner. The injectors are easy to change (easier then plugs) and that will keep your car in a safe zone fuel wise.
I wouldn't run the Iridium plugs either.. just go with some TR55s or TR6s.
Your richness is directly related to the 38lb injectors, again, switch them out until you get to your shop.

ill look at diong this, it just looked near impossibly to get the back ones on under the cowl, or atleast my lazy half beaten memory tells me so ( swapping an engine in your driveway alone with a shop crane can be taxing haha ) Thats what my thought was. Going to look at it right now. As far as the tuning cost, everyone has told me i would be retarted to pay 800, not to mention the awful history of their customer service in helping me with my car. I have little faith in them, and cannot find anynoe theyve tuned

I'm only a 1/2 hour drive from Speed Inc. too. I wouldn't dream of driving two hours on the highway at 1800-2500rpms with injectors that big =-o
I'm also a firm believer in the standard copper TR55's. No need for the iridium stuff unless you're trying to save weight for the track (lighter wallet).
LOL, my wallet has already been modified for weight reduction, trust me!
Anyone who has ths prob and stumbles onto this thread, DO NOT DRIVE YOUR CAR WITH BIGGER INJECTORS UNTUNED!!!! I drove it to muffer shop and back and it wouldnt crank and i had to pull EVERY plug and clean it, totally fouled em up, and had soupy oil from all the gas getting into it. Borrow/rent a trailer or do injector swap as suggested, IT REALLY WILL MESS YOU UP DRIVING LIKE THAT, EVEN FOR a few MILES!!!
PS. Once there it took Rhino79 about 2 minutes to pull enough fuel to crank it and idle. Its just getting there is the challenge, I trailered it 2.5 hours to avoid driving with those injectors, and it was DEF the only way to go

Good to hear you got it fixed.
And :doh: the washing down of the cylinders and/or contamination of the oil with fuel was something else I thought about mentioning but failed to do so
