preventing low end torque loss??
I understand there is a dip in low end torque when you put on rinehart true duals. Can or will this be prevented with a custom map or maybe 2.5 baffles rinehart offers. Any info would be great.
I will be running SE ac and TTS mastertune as well

2 1/2" would give you more dip than 2". You generally have to richen the low end from idle to around 2500 rpm about 3 to 5% by increasing the VE's from low to 50% load or 15% throttle position. If you have the factory timing increase it at idle area to about 22 degrees then progressively go up to 38 or so by 2500 from low to 60% load or 20% throttle opening. I also increase the ve in the 100% load or opening area from 2000 to 4500 10% and increase timing in same area 3 or 4 degrees. Do all this on both cylinders. You may also want to increase the acceleration enrichment 0.3 and lower the decel enleanment about 0.2 This will give you a good starting point. If you are running a TTS performance map these numbers may already be changed over stock.
