Default to laggy

well its heres my deal i got a ecu flash from kingpin , and map clark a.k.a azscoobie built me. as it hits boost the car start to kick then when it hits 4500rpms it hauls ass..

i have a 4eat, automatic tranny.

my mods:
+Perrin FMIC**
+565cc Sti Injectors
+Walbro 255lph Fuel Pump
+helix upipe
+invidia downpipe
+blitz full racing catback exhaust
+Perrin Lightened Crank Pulley

my ecu tek is sort of a custom map but didnt get to play with it on the dyno, he built one map could falsh the ecu, so i boguht an ecu from kingpin and he flashed it..

i put a star next to perrin fmic cause i was thinknig maybe thats why it lags so bad but has killer topend!

its 100ferenhiet her in houston and 80% humid, is this why? think c02 spray to the intercooler will fix my problem?

I have an almost identicle setup as yours as of yesterday.... but no reflash/manual/TMIC

SR40 now but....

Based on my knowledge that I have had the VF30 combination for over 50000 miles I can say that something is a little messed up my VF 30 kicks in hard at around 2800-3000 RPM. The VF30 should spool much earlier than 4500 RPM even with the FMIC. Do yourself a favor and buy DeltaDash and do some logs. Send them back to Clark and have him adjust it.

With DeltaDash you can load in the new map that he provides you without sending the ECU back.

As far as O2 spray, I doubt it will have any effect on your spool, may run a bit cooler and aide in knock supression.

Yeah it still seems a bit laggy to me. Some logs would be great if you have them. Bosst leak is most common cause of lag that we see. Might want to recheck all of your FMIC pipes. Even a small leak can cause considerable lag. The FMIC has some effect but I would exspect it to be on ealrier than it is. Let me know so that we can help sort this out. Thanks.
