Whats the highest HP shot of NOS can our CLS take stock?

And with a Fuel Pressure Riser/Regulatior?

All depends, I bet you could get one shot of 200 in.


But in all seriousness i'd say 50-75.

 

i have been running 75 shot for 2 months and been fine so far

 

And thats with no fuel pressure regulator/riser?

By the way do u have a rich/lean guage?

With that kind of hp shot the only thing that would go is ur tranny, right? Or does ur system know when it is running too lean and cuts off?

An adjustable FPR is really irrelevant. It can increase the fuel pressure but if the pump is not up to the task your SOL... The fuel pump is the first weak part of the fuel system when wanting to run more than a 50 - 75 HP shot. The stock pump should be supplemented or replaced when running 100+ HP shots.
