You will definitely feel a power increase, there is no question there.

I just updated my AP to the latest firmware...then put it back in my closet

 

Really? I was actually considering getting a protune soon, but if these new maps have even a little bit of an increase over the old ones, I'm thinking I'm gonna hold off on the protune haha!

 

Oh, wait a second, I think I got a bit confused, I can't vouch for any gains between the old vs. new OTS maps, I have no personal experience there. I was referring going from stock to flashed! I say give it a shot and let us know though

 

Damnnnn got me all excited there hahaha.

 

yeah you can definitely feel the different from stock to coob tuned. pro tune is the way to go. My trouble is I can't find a shop to do coob pro tune for me.

 

Take a little day-trip and visit Jon Drenas @ SoCal Cobb.

 

sounds like that's the only choice. ;-)

I need to do a few more upgrades before I make that trip. :-D

 

Nooo I meant a difference from the original OTS tunes and the beta tunes (200v maps) trying I find out if you feel a power difference between the old tunes and te beta ones

 

I haven't try v200 maps yet. I mentioned that I've been running v302 maps since last September. apparently v302 and v200 are the same. However I jumped from stage1 beta to stage2 v302 along with intake and full cat back upgrade so of course it was a huge different.

 

V200 felt little faster compared to old V300 maps, or maybe it's just me..(Stage 2 with Cosworth vs Stage 2 with Stock tune)..but I used to hit 26-27 psi today I saw a few 28psi with the new map..

 

With the old stage 2 and a full TBE intake and upper i/c pipe I'll see spikes to 27 and 28. And actually every time i shift at WOT and go WOT again in the next gear, I will get a quick spike to 29, could never figure out why haha.

 

should I switch to v200 stage2 stock air box? I'm running v302 stage2 Injen intake. It does sound like I would do a downgrade....

 

So I JUST read the notes on the beta v200 maps.... The peak boost for the old stage 2 maps is 25PSI (+/- .7) The beta v200 maps state a target peak boost of 28PSI (+/- 1.5) So I'd say anyone using cobb AP is going to be seeing some gains when switching to these new maps.

 

the Stage 1 and 2 2008-2010 maps have been updated to the same spec as the 2011 (all mapping etc)

 

Going from the old stage 2 to the 200v one... How much power do you think we will pick up?
