hey guys I have an 05 coupe MT with 28000 miles

im done with looks and moving toward performance

im thinking MREV2 with 5/16 spacer from motordyne with stillen sways and grounding kit

i have test pipes but im considering Berks HFC's to cut some raspiness

what kind of gains can i expect ?

also how big of a power difference is there between test pipes and the berks HFC's ?

if anyone can post a dyno graph of this combo it will be greatly appreciated

and is there anything else i can mod on the engine besides exhaust without going FI and tune ?

thanks everyone

 

Get the MREV2 and spacer. Changing the Final Drive gearing is a nice mod too.

Why don't you want to get a tune? A custom Uprev tune will give you the best gain.

 

arnt they pricey ? how much would and uprev tune run me

 

^$500-700 (rough estimate)

 

Check out the reviews on my grounding kit and PM me if you are interested in getting in on the March special.

still only for cali or can i get them shipped to florida

 

^oh yeah..thats an old thread. I can ship it to you as early as tomorrow and it comes with everything you need to install including step-by-step instructions with pictures.

 

Thanks, I'll take a second look at it tommorow. still comes with the line to the tranny ?

 

yes it does

 

il search the forums for the power gains people are getting from uprev, thanks

do you have a tune currently?

 

Yes but its with FI.
I used to use a preset map with the Cobb accessport which yielded a 10/15HP - 20TQ gain with supporting mods. But you will be able to achieve more with a custom Osiris tune.
Member Jairen has an 05 6MT with Uprev and has a dyno sheet somewhere on here.

 

Im not too familiar with getting tunes.. so if i get the uprev or osiris tune it come wait a cable and cd.. could i do it myself using the software on a laptop or would i need have it professionally done on a dyno ?

 

I'm not too familiar with the cable and the CD, I don't have them. You will definitely want the car dyno-tuned by a professional, see if there's any authorized Osiris dealers in your area. Maybe someone will chime in regarding the cable and disk.

 

Alright, I know Seminole Power Sports in my area has a dyno... if anyone knows how well they are at tuning

im thinking about getting some base numbers and taking it up this week

thanks for the input herrschaft
