i am running a 1997 e series engine the injectors are ab when i get on it i can hit 1200 i flipped on the 10 k mod and let off at 1250 im running a good down pipe 3 inch then it goes to a 4 inch pipe and a muffler. im running a late modle air box 2002 with the bottom cut out of it my boost is at 23 pounds am i over looking something should i ditch the muffler? or the air filter the engine has 9,000 miles on it and im fixing to tow about 8,000 in a couple of weeks thanks travis

I would suspect the air filter not flowing enough and also look at the cat converter. The cat may be restricting.

If you are hitting those temps unloaded, loaded, will be a real problem.

My truck as it sits can hit 1200 no problem empty. But it is 100-115 outside. HJavent had the new mods long enough thought for winter yet.

I don't think ya really have a problem, you can control the temps with the right foot [img]/ubbthreads/images/graemlins/laugh.gif[/img]. Keep the rpm up around 3k when hitting the hills and ya will be fine. I would look at getting a Tymar intake and a flip chip.

I can hit 1400 with AD's and no intercooler... I don't keep it there long though, just long enough to get around my brother and his 01 Cummins... Yeah, just keep control of the EGT's with your right foot and you'll be fine with 1200.
