There's nothing on valve cover. Where else can I get the info you need?

What does AI mean? I'll look at the valve cover tomorrow. My concern is if I put Rochester injectors and turbo on it, will the lag go away? I have their stuff on another truck and love it.

I just bought a 2003 RD688SX tandem dump truck. It has a 8LL and 400. I really like the truck. It pulls well but has a two second lag between when you lay the fuel to her and when she starts to hunker down and pull. I intend to put a bigger turbo and honed out injectors on it, but am concerned that this lag will still haunt me. Have anyone been down this road?

Do you have a gauge for boost? What are you reading on those long pulls when pyro goes up? My boost snaps up to 35 PSI and stays there. Rochester's turbo is $2,200. Well worth it. Have you smoke tested the truck since the new injectors?

When you guys are referring to stage 2 or 3, whos injectors are you using? Did you put bigger turbo on with injectors? I've done two Mack E7 400's with Rochester parts. Both made a tremendous difference. My pyrometer never gets high. My first one was 2.5 injectors. The second one, which I still own, is a stage 3. It passed a smoke test with no problem.

I paid $2,200 for the turbo. I don't know if that's cheap or not. It works great with the added amount of fuel they're injectors flow. I did the second installation three months ago.

Yes

I've done two E7 400's. Both ran great!! One was 2.5 other was 3.5.

Got a Bristol Donald look to it. Very cool.

Call Rochester Diesel. I've put his stage 2.5 and stage 3.5 on my trucks. Definite usable increase in power. He'll send you a new turbo and necessary rubber fittings to make it fit, and honed out injectors. He'll want you injectors for cores. Both trucks I did were E7-400 Macks. Both drove GREAT afterward!! Ask for Brad 507.288.8038

Transmission has been sold. Thanks.

It is mine. I think it was sold today.
