OK guys,

I've been following this thread and now I'm wondering what the correct BOSCH injector upgrade part number is.

Is it the M-Benz injector for the CLK/SLK version of the W112 3.2 V6?

If you just drop a six-pack of M-Benz injectors on a stock Crossfire N.A. motor will you see any power increases ? Or will the MAF and O2 sensors just tell the PCM to reduce injector duty cycle and put you right back where you were ?

My last attempt at modding a "modern" MAF/O2/PCM set-up was a '97 FoMoCo 4.6 V8 SOHC "Mod Motor". Upgraded the exhaust, throttle body, larger MAF and PCM tune but topped out at 250 Hp because the 19 Lbs/Hr injectors were starting to "max-out". The later "product improved" Mod Motors featured 24 Lbs/Hr injectors and were good for 300 Hp.

I know I'm comparing a 4.6 V8 to a 3.2 V6 but to produce "X" amount of power you need "Y" amount of fuel. So I don't think you can ever expect to top 250 Hp using 17 Lbs/Hr injectors.

So...swap in a bigger set of injectors and let us know what happens !
