Approximately, how much will the smarty box alone gain in HP/TQ on a stock 2001 Sport (non HO)?
How much more If I add the 275/RV injectors?

Thanks,

Dave

The smarty will add 65hp and the 275's will add around 40 hp. Most people that run the EZ/275 combo dyno real close to 300hp. So since the EZ and the smarty net the same peak hp you would also be around 300hp with the smarty/275 combo.

a smarty and some rv's, like stated above, will put you in the ball park or 300 hp.

My 2002 HO neted 256 HP on the dynojet with just the smarty. My friends 2001 SO with smarty and mach 1.6's netted 306 HP.

What about some trq. figures? Does anyone know the amount of torque the smarty adds?

My torque was 511 on my 2002 HO

Wow! I thought the smarty would put down more than that!? I guess it's just better than a EZ and maybe a few other fueling boxes because it fuels harder down low and no need to do a wire tap(unlike the comp and soforth). Is this correct?

The way the smarty fuels and adds timing is what makes it so desireable. The smarty can makes overall drivability much, much better...

So what is the process of switchin to a different. I know you have to download it or whatever. Do you just plug it in and do it from there or do you have to go through the whole computer process again?

dieselfan

plug it in, it takes about 2min. truck must be off.

RowJ

Correct!

Thanks dieselfan I appreciate it. That makes me consider it even more now.

Sorry guys no baseline. We had a truck just like mine come in that same(Dyno day)day that put down 187hp stock. Not sure the torque.

Smarty gained 76 hp on a back to back dyno test this past weekend; 24v with an HRVP-44 and Jammer 2 injectors......
