has any one running the stage one with 93oct had a problem with boost cut in 4th and 5th gear? just had mine installed today and the map i got from vishnu is pushing 25psi underload in 5th gear. that cant be healthy. does anyone one else run that high and if soo do you have the same problem? thanks guys.

 

oh but other than that the car is a rocket compaired to stock. so its not all bad just cant use full throttle.

 

Go to your boost map and hit the "<" three times in every cell between 2500-5000rpm.

 

25psi seems high, although I've noticed that I can get my stage 1+ setup to spike to 24 when I roll on the throttle in 4th and 5th - if I gun it, it just goes to 22 psi and tapers off. Are you running an XEDE/XEDEflash combo? and are you using the map off Vishnu's site?

Check your vacuume lines. You might have a loose one causing overboost. Just a guess....

I've zip tied mine. Some of them have popped off at 28lbs

 

agreed

 

i would but im still waiting to have my lap top returned from best buy they hav had it for 3 weeks. i think it has alot to with the cold dense nh air and the fact the map was made with simulated 93oct and not from the pump.

but thanks for the help ill try that whan my lap top returns.

 

Thats not it we tunee 100+ cars this year on 93 in multiple states. Its cause your boost is too high
