Alright I got a small problem.just had my car tuned at a local shop with hp tuners they did a great job tuning it but if I drive it it across town 10 to 15 mins it slowly learns down from full boost(23-25 pounds) down to about 9 or 10 pounds.if you unhook the battery for a couple minutes it goes back to full boost And starts the slow decrease to low boost.i searched on the forum for awhile and can't seem to find anybody with the same problem.if anybody has any ideas I can bounce of the heads of the shop it would be awesome thanks

 

Do a search on hpt forum I remember reading how to get around the learn down but cant remember where or how it was done. Ill try and search for the solution
Please report back if you find the solution

 

Get it tuned properly, "learn down" isn't something you can turn off, they didn't adjust the desired torque tables.

 

Op if its going into learn down... Its not a good tune

 

That's what I'm thinking it is.im just trying to do some leg work when I take it back in.ill check on the hitting forums but I think it's the torque tables just need to figure out Wich ones.

 

Try this link. LNF Guides

 

I think maybe they didn't adjust the torque limit tables or desired air load tables. Maybe post up a copy of your tune if you can. Or just ask the tuner to adjust it properly. Have they tuned LNFs before?

 

Hey finaly getting back on the forum but my remedy for the learn down ended up being my charge pipes(zzp) were rubbing up front and it was enough to make the computer think there was a knock so it kept pulling timing.not something I would have thought of but its working great and man its a beast of a car now that it's tuned right! !!
