As long as you have enough fuel supply you should be fine at the 150hp level.

If you could add a signature with the major mods to your car it would help with knowing what we are working with.

I see you have the timing twister but you don't mention a custom tune or programmer. On the stock tune you might not need to pull any timing, but at most 1-2*.

Please let me know if you have any questions.

A 150 shot kind of ries the line of needing a 255 pump. Make sure that FPSS is wrking.
