last time i went to the track, i ran a 12.6 @ 118mph. only thing that has changed since then is now i am non-seq and i added a diff brace. I ran the same shitty 2.3 60' as i did before, only now i ran constant 13.3's @ 111. where as before i was running constant 12 sec passes.

i actually ran into cam from pettit out there, he said that runnin non-seq should not effect my mph and how the car drags.....any ideas?

I donut have any ideas but im almost 100% positive it shouldn't effect your times.... Is it full non-seq, poor man, etc?

What's your boost pattern look like? I know you're non-seq, but is it a rock-steady boost once it hits until redline?

it spikes like 15 then holds 13.5~ and does hold solid till redline

Did you tune it after converting to NS?

i dont think they adjusted the tune.

Have you got a datalog of the run?

Personally, if I changed oil brands I'd get it tuned again out of pure fear.

change your plugs.. use different fuel and try it again..
although if she werent tuned for nonseq...

Non-seq should mean nothing in terms of the tune, at least above 4500rpm.

I would think non-seq would make a difference. You won't be at full boost until a higher rpm, so I would think it would affect your 60' time quite a bit. Which is why your trap speed didn't really change, but I bet your 60' did.

He states that his 60 foot remained the same, but his trap speed dropped by 7 mph, which is a very significant amount......

You should be physically able to feel the difference of -7 mph. trap if you were used to the top end power. Sounds like a hiccup somewhere in the new set-up. Slight exhaust/Boost leak? I double check all of your block plates and nipple/ caps. G

Wow, I really misread that one. Sorry.

Or maybe you just suck at driving.

Come to realize that 118 seems strong for 324 rwhp. Your current trap speed is a bit more on line. 111 to 114..

I've heard that you can't use sequential maps on a non-sequential setup:

Well I just had my car tuned by steve kan a couple weeks ago and he said if I go Non-sequential I wont need to change my tune at all. So maybe its the way he tuned it but I think it just doesnt matter wether you sequential or non.

Real nice antonio.

You most certainly should not run a seq map on a non-seq map, and vice versa. Why? because you're seeing different boost at different rpms throughout the rev range. Seems pretty obvious to me......

GoodfellaFD3S

iTrader: (213)

He most likely tweaked the fuel values for the applicable pressure and rpm cells you'd see if you ever went to non-seq. Regardless, if it's my car, I'd still check AFRs after a change like that.

efranklin

Yup, now that i think about it, it makes sense... Your probably not hitting full boost until 3,500 maybe even higher, whereas on the stock twins you were hitting full boost earlier.
