i think thats mostly it..but my question is im still getting a studder when the secondaries are coming in and i was wondering wouldnt this be because of the larger injectors be hitting an extrenemly rich spot? and how harmful is this to my motor to be running this setup untuned?:Wconfused

the studder is a common problem in 7's. new rtek 2.1 fixes it. only way to fix it other than a standalone

and dont tune it until you get a wideband or dyno it with a wideband

you'll just run really rich. wont do any harm other than to ur wallet :)

ok cool. well im getting a wideband next weekend so ill keep this thread updated and let you know how it goes. thanks
