I am new to tuning and have just did a 305 tbi swap to a 355 tpi speed density system with a manual tranny. Im starting with A stock bin and 8d xdf file. The problem is at idle my Blms stay at 108 and dont move till i rev it a lil bit. The INT is around 124 and IAC count is at 22. I do have a bigger cam XR276HR-10. Duration @ 0.006": 276° / 282°, Duration @ 0.050": 224° / 230°. Max Lift w/ 1.5RR: .502" / .510". Like i said im new to tuning im using ostrich 2.0 and tunerpro rt any help would be great.

 

speed density....

Looks like you need to address the VE tables. Seeing your INT is not bottomed out it appears you did get correction at 108 BLM. How does it drive?
