Only 288hp at 5300 RPMs in 3rd???
I dynoed my truck a while back and it shifts out of 3rd at 5300 every time. It did 288hp and somewhere around 300 ft lbs.
In 2nd gear it would only do 235ish hp which he said isn't an accurate number (obviously) but it did show hp climbing all the way to around 5800 rpms.
How are yall keeping it in 3rd gear all the way throughout the RPMs? We dynoed about 12 or 15 hemi cars that same day and none had this problem
Mine is an 07 with an ATS trans, supposed to be a 3k stall, pacesetter long tubes, gutted cats, x piped and dumped, 4.56 gears, intake, diablo 93 octane tune and moes 87mm throttle body. I figured it would do about 315-325 hp.
I've heard diablo is having problems with trans tuning. Could this be part of it? I've never updated it and I heard that the update is what screwed up the tuning. My shift points are raised 1-2 and 2-3 and it shifts pretty hard.
