I meant what ET did you run in MSM when you trapped 106

 

I think it was 13.5 or 13.6
I was on 205 all seasons, they simply didn't grip at all, ever. I think the only pass I did decent was launching in 2nd

 

Moving this to the builds section.

Re-Tuning OP's car, ran into a really weird issue and posting up to try to speed up diagnosis:

After his new engine, VE map is really odd. Car requires a LOT of fuel up to 100kpa, then requires VERY LITTLE VE in boost. We already diagnosed and replaced a dying fuel pump (or more likely just way too weak for this setup), but now his latest log shows a requirement of 100VE at idle, and only 94VE at 4k/10psi (or thereabouts).

Faulty FPR? (though logic dictates that the symptoms would be backwards if that was the case).

I will post a log when I get home.

 

Maybe adding the FMU was not the right approach

Still the ID 725's? What is rest of fuel system? Post tune as well?

 

Yeah, if he has an FMU and it's adding fuel for you you would get what you're seeing.

 

No FMU.

NA8 block, 84mm 8.6cr, bp4w head, ported with backcut and tapered stock size valves, ST double lite springs, FM Mani and DP IC pipes and IC, GTX2860r gen 2, NB fuel rail, 94 FPR(just tested today to be good) NB IM, ID725, DW200, LS2 Coils.

Ill let vlad upload tune as he hasnt sent me the revision he is talking about.

 

I was joking.
