Hey Cincy! long time......hope your build is going well.

Got a question for ya sir, I have a 2001 225 with and APR 3+ kit on it. With the MAP sensor that comes with the kit, the car should be able to run 25-26psi of turbo boost. Well I cant get a straight answer as to why me car will go into limp mode when I run more than 24lbs. 1st and 2nd gear is not a problem, but when I ring it out in either 3rd or 4th gear it shuts right down into a hard limp. Any ideas>> Thanks!

 

Have you scanned for codes or talk to APR themselves? I would do that first. Im not sure why it would shut down above 24psi. The stock map can only see to 22psi and people dont have problems running 30psi on it with uni or tapp sw

 

No codes. APR has just told me that it could be the MAF ot the N75.........I bought a new MAF and I have a new n75 plugged in but I have it bypassed using a manual controller. I am clueless

Thanks for the help buddy!

 

The only thing i can think of is the mbc works to fast for the sw. Its not really likely, but i guess it could happen. See what happens with just running off the n75

 

Well thats a pretty good theory. Its worth a shot......I'll try it tomorrow and give you a follow up report. Thanks
