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?

 

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
