Got my Mach 4.5's installed last night. I haven't driven much with them yet, but did a 4th gear romp with Smarty on SW2 and Drag Comp on 5x3, and I noticed more power all the way to redline and tires broke loose. I'll report results after some more seat time.

Anybody want to by some DD3's ?

 

Possibly. I've been looking for a small injector for long trips.

 

Time to update your sig, get on the rollers, then update it again =P

 

I am interested for the right price>>>>> Let us know soon. I also have my eyes on a set of DD2's.

 

You notice any change in the smoke?

I went from M1's to M4's and it amazes me how much cleaner they run. The M4's rarely blow black smoke except below 1400 RPM if I stomp the diesel pedal too hard. But there is not any power there anyways. Otherwise the smoke is almost always grey. Ussually just a short spurt of grey after shifts, then once the right boost comes on the exhaust goes clear and I'm gone.

They seem smokier in the lower rpm's but they clean up pretty good. They pull much harder on the top for sure. I'll post more results in a couple days.

 

My piston tops and bowls looked real good after running the M 4.5s for many miles and 1/4 runs.. No hard carbon build up at all, could with them clean with a rag.
