i'm going to a 7670, actually. the 8374 would be a bit much for my purposes and i prefer responsiveness over whp numbers for my application, haha. you are going to make gobs of power, though!
that's awesome you have your order placed. did you go EWG or IWG?
you want to have your car back up and running by thanksgiving with your newly ordered TS EFR?!! i doubt i'll have my 7670 this year and your 8374 won't be in even after those and you know how many folks are ahead of you. i dont know sir, i think you should plan accordingly for a february/march receipt of your 8374.
regardless, it's gonna be bad when you're done!
