The trip computer is wrong after the installation of this device because it alters fuel delivery and fuel consumed post ecu.

The only thing that changes with shifting is it defuels a little less. 7ou can feel it but it's not a big deal.

The alteration to the infection pulse(s) is post ecm so the computer cannot tell. It can see mass airflow, and things like that. However, that's deep into the grey area. Injectors are an output not an input, so they cannot "sense" the duration of the pulse. It just commands a longer pulse than...

They alter injector pulse. It's for ppl who want to keep their warranty.

Any special tricks to getting invoice pricing and where does invoice usually fall compared to Msrp?

How much under Msrp are you guys paying to get out the door minus taxes (don't have that here). Cc lariat 4wd diesel. Best I have seen is about 7k under Msrp. 55 for 62 list. Thanks

The 6870 is almost dead nuts 200rpm slower to make full boost (45+psi) than the 6466. The 6870 doesn't give up even 50rpm to the 6766 and has noticeably cooler charge temps when you run it with the H cover. It makes 100whp more than the 6766 anything above a reasonable pressure ratio. I'm...

Yes does anyone know the TSB?

No warranty here but have lazy into reverse and sometimes it misses the 2-3 shift completely and free revs. However, it is lazy into reverse after driving home, not after sitting. Is that a pump issue?

Update us on what exactly fixes it. I've got lazy into reverse and an occasional miss on the 2-3 shift which I'm hoping is just a solenoid.

I'm also interested

If it is your post IC air temps, and they are lower than what the PCM would expect when climbing a grade that's a great thing. I'm not sure the logic that the computer uses but with other vehicles they look at the pre/post temps and if they vary too much the PCM assumes there is a leak or a...

How much later than the stock turbo does it light? Also, when cruising at 60-65mph on flat ground in 6th does it struggle to stay on the charger? Thanks for the feedback from someone pulling with their truck.

Looks like its PWM modulated like a boost controller to me, but I could be wrong!

Still would love to know if one of the tuners can kick on the fan clutch sooner. Coolant definitely will get to 230 and oil temps 240's even with a light load if you're pulling a big hill. I backed down to the lowest tune and EGT's stay nice and cool but coolant and oil temps still get pretty hot.

Is there a list of table descriptions?

Yup same here. When crawling up a steep dirt road in first the temps really climb. I also see coolant temps In the 230* range ******d on a tow tune.

That's high, my trans never goes about 210 even towing heavy up big passes. I noticed a lot of guys are in the midwest where it is flat, I'm always pulling over huge passes which is a different story.

I have not had my truck defuel but towing not even that heavy over a big grade I also get crazy high oil temps and pretty high coolant temps. Its really disapointing. The fan clutch will lock up but not until the truck is really hot. I'm going to add an oil cooler as an addition to the stock...

I'll take one! Do you have a link or whats the best way for me to purchase?
