High EGT's after upgrades

Need your help. I just did a Barder 1.5, Ported Intake Manifold, Driven Diesel RR, S&B CAI, Metal Cold Side Pipe with Riff Raff boots and a TB 4" Exhaust with no cat. I am on a stock fuel system and injectors. I also removed the scoop in the uppipe and welded a steel freeze plug in the uppipe side of the EGR cooler. I have done the bulletproofing and the FICM repaired with the Atlas 40. Stock wheels and tires. I started an other thread about MAP, BAR & EBP (Here : MAP, BAR & EBP ). I am hitting 1300 degrees with the stock tune going 70 mph at 10lbs of boost on a slight grade. The SRL+ nets me 1250 degrees. This combo should give less EGT's not more. I am pushing way more air. Everything is tight. So all you guru's, what am I missing?

Possiable boost/exhaust leak, also have you had your tune updated yet

No leaks. Everything has been double checked. Just got the SRL+ from Matt today. It also does it with stock programming.

Don't you need tunes specifically for that turbo?

Yes the SRL+ address all the upgrades. Same route for 3 tunes. Stock, SRL+ and IDP Xtremes. All high EGT's. I ordered a new EV2 Pyrometer tonight just to rule out the old pyrometer that was used in 3 different trucks and purchased in 2004.

Bro, if you're truly hitting 1300+ degrees going 70 w/10 psi of boost, then you either have one major exhaust leak or your turbo is producing a TON of back pressure. Either way, it's not spinning very fast and you are probably using a lot of throttle to maintain speed. If you are not using more than like 30-40% throttle, then your EGT gauge is screwed.

I am going with exhaust leak also.


10psi at cruising is pretty high. How big of a grade?

Does it jump right up to 1300 or does it slowly climb up to 1300 after a minute or two of driving?

What size tires are you running? Bigger tires at 70mph could be slightly lugging the motor while going up hill

What are your rpms? Going up a hill with the 10 bladed turbine runs best above 2000rpms

I don't have a leak. Stock tires/wheels. 3.73:1 gearing. 70 puts me just under 2k rpm's. My EBP reading on the SC2 was 26 - 28. I did order a new gauge tonight. I'm stuck. This makes no sense.

It gets to 1300 pretty fast and holds.

10 psi @ 28 ebp cruising @ 70 is crazy. Check to see if map hose or barbed fitting got damaged.. is it possible a hotter ficm tune was loaded. If it holds 1300 that is not bad.. what is vgt% and maf??
