This is a discussion on Just ordered my Cobb AP within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; Originally Posted by ElVerde Heyo! This is mostly a brag thread, but I'm just so excited that I finally pulled ...
Ok, so my first impressions of the Stage 1 map are "holy hell why did I wait so long to do this sooner!?"
The most noticeable thing initially is how much smooths the car pulls. Idle speed feels lower (about 700 rpm) but the car is much less lumpy and jerky. It really feels like a totally different car. It is also noticeably faster, pulls harder, and pulls sooner than it used to.
The kartboy knob is better than expected. It's heavier than I thought it would be. It is much smaller than the stock knob which I like.
I haven't had a chance to install the shifter bushings yet but I'll give you guys an update when I do.
Only the front bushings for now...from what I've heard they make the largest difference and the rear bushings will increase noise in the cabin a lot more. I may add the rears later on though.
I've gotta say, the Kartboy knob is really growing on me. It's about half the height of the stock knob and makes the throws feel shorter and crisper. I'll get some pictures up later for you guys

Yeah, I've heard good things about the Perrin maps, so that should work out nicely for you. You should be able to run either Cobb or Perrin maps on that AP, so you'll be fine either way.
I'm seriously in awe at how crappy the factory tune must be on these cars.
If you've installed them, then you know infinitely more about the impact the bushings will have than I do...So I can't really argue with you.
Good news is that a member on here is selling his rear bushing to me for 20 bucks...so I won't have the chance to find out whether it's true or not. both bushings will go on the car at the same time.
If you like the improvement of the front/rear bushings, you need to install the shift linkage ones.Originally Posted by ElVerde
answered a lot of my questions... the cobb access port is amazing I dont know why anyone would get perrin or w/e.... stage 1 is great imo but stock wasn't really all that bad. Its not night and day with me but im really suprised that stage 2 is only 316 hp.... over stage 1 which was not much less... is stage 2 cobb with aem intake and dp safe?
Because Perrin gives you a free map of theirs if you order the AP through them. The contract for being an authorized AP dealer states you can't sell the product for less than MSRP, so in order to entice customers, dealers can only throw in extras to help "drop the cost". Having the option of using the Cobb or Perrin map is nice.Originally Posted by SPT2011Stock tune is garbage. As I posted earlier, there's more to the difference than just peak numbers. Area under the curve and overall driveability are more important factors.Originally Posted by SPT2011
As for a Cobb tune being safe, every car reacts differently. The only way to tell how well your car is taking the map would be to datalog. I've datalogged AP maps that are knock-free, and others that pull timing on every WOT run.
+1 on the perrin maps. It makes sense if you're interested in running a perrin map because perrin charges something like $180 dollars for its maps alone.
Whether stage II is "safe" is a difficult question to answer. Generally, Cobb has been regarded as fairly conservative and "safe", but as the previous poster stated...this can vary based on your car. I'd recommend datalogging your car.
So far everything is going swimmingly with my Stage I map...I'll be putting on my AEM intake and flashing the 91ACN Stage I+AEM tonight, so I'll report (with some pictures) on how much of a difference that feels like!
