Ok so, I have an 04 5AT Coupe, 93k.. Mods, Injen CAI, Motordyne 5/16 spacer, Megan Testpipes and Ypipes with no resonator.. I have no idea how much hp im producing but im really lookin forward into gettin a Tune. Basically get the maxx out the car.. What you guys think? Also about how much will a tune cost?

 

Osiris custom tune. End of discussion.

 

I was told i would gain about 10whp.. will i even feel the difference?

 

if you go with the osiris then you should gain more then 10 whp with a proper tune from a good shop. there are many threads. so if you wanna spend the 700 then 700 for a tune and get the max thats the route

CHEAP ROUTE cobb accessport. prolly gain about 10 whp. no dyno. preset maps

 

I spoke to a shop called Vinny Ten Racing, they work with turbo G35 and Z's. he told me about 10whp thru the phone..

 

well maybe you should look at the dyno graph for the work that they did on car of grocrygettr who responded first to your post. he had i believe a 30 whp difference between no tune and his full osiris tune. so you can choose to believe whatever words people tell you or you can look at the dyno sheets and see the true information
