can anyone fill me in on how well this device performs? any issues with it. it seems like it should do what im looking for, but i want to hear from you guys.

 

Are you going FI eventually? for NA it all depends on what you have in your car and it will give you a good 10 - 15 more HP but that's with a Tune. Most that i've seen are using UTEC for NA application.

 

eventually, yes. but not for quite some time. for now im thinking more along the lines of test pipes, headers,exhaust plenum etc. i do have a guy who tunes about 10 houses down the road, and he already said he'd do it. (tuning, not butt sex!) i wasnt really thinking of the greddy for HP, but more for keeping the AF mix right. obviously, if i can squeez more HP at the same time.. great!

 

I think to really break the magic 300whp you'll definitely need a Tunable EMS so it will be a good investment. adding those mod will definitely put you on a lean side but not much so if you have the money i say go for it not just it balance your AF but will be able to squeeze at least 10 more horses... Will you be getting the EM Ultimate? Did you consider UTEC? either way there's an advantage. Power to Price ratio suck though..

 

i would use UTEC instead
