Hi all, just a quick thanks to the efi live team for the VVE tables, makes life alot easier.:notacrook:
we have been doing lots of E38 speed density tunes lately, the one that caught my atention was a 2007 VESSV with a totally stock engine with the exception of a cam and valve springs which made 395RWHP,.
A vortech V2 blower was added along with the T REX fuel pump, which resulted in 548rwhp at 4800 rpm, the afr was tailing up, the pump could not keep up to its task.
So the t rex was swapped with a bosch 044, we were able to rev the engine past 4800rpm, first dyno pull 608rwhp.:eek: thats was with the afr flatlined at 10.7:1. (the dyno afr will not read below 10.7)
I trimmed a little fuel, 639 RWHP, thats still with the afr flatlined at 10.7 lol! i dare say the afr on the first run would have been in the mid 9's considering we picked 31 rwhp with a flat afr!
thanyou EFI live.
