Engine reduce power - Twin turbo

[Benltr]

Poor times.

The max effort tune acted very weird and was slower than the street tune.

I managed to do a 12,39 at 109,3 mph on the street tune with a 1,75 60ft (which sux)

The autocal doesnt recognize my truck, cant datalog without errors, cant even know what DSP # i am. The 12,39 run might be on whatever tune i dont even know since i think they are all messed up.

Truck weighted at 6580 pounds + 250 (me).

Something isnt right and i called Dustin this morning, wait on his call back.

No boost leak

The max effort tune acted like a shot of nos.

Hit hard, then slow and than hit hard and than slow and than hit hard for the end.

Like 2 flat spot during a 1/4 lenght

No problem with the trans, shifted firm and good. Still wondering my shaking when engaging reverse too.. (other post)

The last past on the max effort was 13,08 with a poor 1,90 60 ft (spin off the line) and the best with the max effort was 12,50 at 108 mph

Yes, thank you for calling me back fast and helping me out why my autocal. I'm sure Rob will find out, sounds like a rail pressure like you said.

Good customer service ATP :thumb:

Solved.

Harbin is the man, 5 inch intake and no more dic message or bip bip.

Along that, the 5 inch intake increase the turbo sound and the boost seems more steady.

Waiting to test few things at the track but it solve the main problem.

Props to SDP for excellent customer service!

I have had great results with turning B0203 (MAF sensor fitted from "yes" to "no") takes care of the MAF dropping to 0 after exceeding the 79.XX lbs/min.
