352hp/377tq JB4 on Dyno Dynamics

Just got my first dyno's back, mods are as follows;

JB4 - 6/14 firmware, map 2 (14.5psi)
Helix FMIC
CP-e CP/Tial BOV
AA 3" catless DP's
AE exhaust
AFE DCI

95 degrees ambient temperature

Picked up 30rwhp from adding the Helix FMIC, but I also installed new stock turbo's as well. I was going to upgrade the turbo's on the car, but decided against it simply to make resale easier. I don't see keeping the car much more than a year or so and it would have made selling it difficult.

Anyway, I very pleased with the results. On a Dyno Dynamics figure 15% additional on top of that number for 405rwhp, even a conservative 12% equals 394rwhp. I am very pleased with those numbers.

All work done by Buckhead Imports Performance in Atlanta, GA.

I'm not sure what the correction is on this but from the dyno I think its probably 0

All dynos read differently. People are so caught up in peak numbers. What matters is how much of a gain was achieved after installing mods which is why getting a baseline dyno is important...

Am i the only one that thinks this is low for FBO and JB4
You should be at 390's with those mods.

My FBO buddies rutinely put down 390's with 90deg PR heat

I don't remember what the baseline was, but the FMIC alone(and new turbo's) picked up 30rwhp.
