Ok my setup
b18b bottomend
b16a pr3 pistons
b16a head with rev valves and s2s1 cams with AEM gears
b16a tranny with LS 5th.
tuned with Hondata on a chipped p28
(tuned open header) but now I am running it though a Apexi WS catback

OK heres the deal....Just messing around on the streets. I lauch my car at like 3K or so and it takes off strong, shift to 2nd pulls decent (seems to act like a GSR ecu or some **** with IAB) switches into vtec around 4.5 but then seems to pull even harder at like 5.5k.....Well then shift to 3rd and bam down to 4.5K again and that **** acts like I just let off the gas completly.

Sorry if this makes no sense I am tired and ready to go to bed.

I am thinking maybe it is the catback that I put back on after tuning.
I made 190 whp and 140 wtq....Tuned by Stoney at Velocity.

 

Bump cause I just got up

 

bump

 

Up

 

it's probably tuning
try setting the v-tak xover higher than 4.5

 

why are you landing at 4.5rpm anyways? Don't you have a b16 tranny?

 

yea a S1 cable B16 tranny(Hasport Conversion) with LS 5th...

 

your vtec in engaging to soon because my hatch did that everytime at the track. until i took that jdm p72 small box ecu out because mine vtec came in at 45k

 

Did you play with your vtec engagement point after the vehicle was tuned ?
Vtec at 4500 rpms is probably your problem...
Engage vtec too early & loose power as you are describing.

 

No I have not messed with it, that is where the tuner told me he set it. ??? I dont know how I would go about changing it.
