ok i heard that pulling the map sensor on my buddys 24v cr will help preformance and blow some smoke. true untrue? risky? ddangerous? lethay. and what exactly is it and where is it? -

only downside i hear about doing that is that it can wash the cylinders.

But it does smoke more, i think it fools the computer that it is under full boost IIRC.

But i aint a cummins guy -

where is it on the motor? and what exactly does wash the cylinders mean? -

Anyone that tells you that's ok needs to give their head a shake. If you want smoke dump more fuel at it with injectors or a box or something. Pulling the MAP will cause the truck (a CR) to go into limp mode and send all kinds of headaches to the ECM which take some care to remove depending on the year of the truck.

It sounds like you need to do some more reading before I tell you where it is located. Once you do and you still want to pull it I'll let you know.

fuel prices don't bother me its not my truck to buy gas for . but what wyatt erp says makes me wanna stay way away from that. thanks guys. but i still don;t know what "washing the cylinders" means -

It's when you get too much fuel in the cylinders and it washes all the oil off the walls. Which can lead to scored walls and pistons. -
