I've been running the twins now for a couple months. One dyno session is all I've been able to make time for. The truck made 550hp on the same pulse but noticed that rail pressure is dropping on the same pulse that it used to keep perfect rail with. May be filters getting restricted, my be cp4 not being happy. The spool up is a bit slower IMO but top end pulls harder than stock turbo once up on boost.

My son raced it at the local dirt drags and they had a sled pull so I entered it without any prep at all. Snap decision since I was there anyway. Just a local brush pull series with 20 other diesels. Most of the other trucks run the series so I thought I was just wasting my money. Ended up putting 70' on the second place truck. I really like this sled pulling stuff. https://www.youtube.com/watch?v=GIIfnre7cLY

Cool! How has it affected regen frequency and fuel economy? Or still too soon to tell?

I hate to bring up an old thread, but has anyone heard any more updates or had success with Rob's emissions tunes? I just got an LML to replace my LB7 and will be going down to Mike L. again as soon as I pick a tune.

Actually, its good you did. Id also like to hear back from Rob if he found out anything new and how things have gone over the longer period of time....

"Flyin' Brick" 1999 Chevy 1500 RC/SB 2wd -- stalled out, no motivation
2014 Chevy Cruze Diesel -- the DD

Two wrongs dont make a right, but three rights do make a left.

Reality is a matter of perspective.

This forum isn't for the weak of heart.....or wallet.

From mufflerguy on yb,
