ANd yeah, the 60# injectors will be just fine. Anything else done to the fuel system?

 

It has dual gt500 pumps , Mafia lightning extender, Mafia 90mm lightning meter also has stage 2 cams in it , will the cams be ok with reducing boost? and has a 10% overdriven balancer, I don't know if that will affect it also? sorry for all the questions, I am going from a 69 chevelle big block to this , so its is somewhat of a learning curve...but I am much happier now...driveablity is nite and day...Thanks again for all the help.

 

So everything you have will be fine. Which stage 2 cams and are they on a lock out or on a limiter? After market cams and FI should also have a limiter within the VCT system. Just ask whoever installed them.
Some shops do it and customers don't even know it.

The over drive crank pulley will give you more boost. I beleive the GT500 pumps are only good to around 550 rwhp. If you have a dual BAP you will be good to the high 600s I beleive. Would have to look around to see the real answer.

Most importantly, find a tuner that really knows what they are doing. Ask for references or ask here. We are here to help.
