i have a y8 with the greddy kit and i want to know what is the highest psi i can run on the track i have chrome pro with dsm 450cc injectors and fuel pump i have the 15g kit it has been tuned for 8 but will have it retuned if i can go higher.

 

stock map sensor will allow 11psi...most people agree that D's are reliable to about 220whp, but there are a number of them that have gone a lot further. Its your call how much power you want to make...that setup isn't good for a ton of power anyway

 

ya i know but when i go to the track i want to run the best i can

hes been at 260+ for a long time now

 

You'll need a retune if you are planning on running any more boost other than 8 lbs. I'll say get a motorola 2.5 bar map sensor and crank it at 15psi. That is just me though. Check my sig for some d-series numbers.
