post your impressions of perrin 91 vs cobb 91. Got the map from Chris awhile ago, thanks!

 

We actually were able to up the boost a little, since the new software won't throw any codes with adding more power.

We haven't done a back to back comparison to the COBB map, so I couldn't tell you exactly how much more power our maps make compared to their maps. Most customers though purchase their APs from us, and our maps are free for those customers! But I can give you a better deal on the map, I'll send you a PM.

 

Don't know what they changed, but I noticed more torque and its more responsive overall.

Thank you Chris!

 

I guess the "knock retard" log thing in the AP is engine knock. I noticed while driving, my "knock"- if thats what it is recording- went up to around 2.8 at WOT. I switched back to the old Stage 1 map I got from yall and the highest number I say anytime was around like 0.4 at WOT. Is that normal.

 

Ugakirk, it's normal to have a little knock retard, but you might have more if you have an aftermarket panel filter installed. Are you using the stock filter still?

 

I'm using ya'lls panel filter. Maybe thats it. I was just checking. Is that much knock okay?

 

It's OK to have some knock under low or no boost at low RPM. But you shouldn't really be getting any under accel. Are you using the newest map? The OEM map gets a lot of knock correction, ours is actually a lot less, we try to get it to the lowest we can.

 

I used the new map that just you sent me. And then I used the old Perrin map I got when I first bought my AP. That's where the two numbers came from.
