Getting really low numbers on tuned greddy kit
I have a semi customized greddy turbo on my 03 AP1, and had it tuned only to make very low disappointing numbers.
Greddy Kit AEM v2 3in DP/ Single Exhaust Pfab externally gated replacement manifold sos 3bar map sensor 38mm tial ewg 550cc RC injectors (came w/greddy kit) Tuned at 10psi on dynapack (which reads 8-10% higher, or so i've read) I made a pitiful 254 hp and 203 ft/lbs torque. Graphs attached. Is this normal? I thought numbers closer to 300 were more common. https://cimg8.ibsrv.net/gimg/www.s2k...cf194e36cb.jpg |

I have also read that Dyno-Pack will read lower! This has also been backed up time and time again.

Yes I have read that too by the internet, however since my car is being dyno'd on a Dyna-Pack I decided to look into it further.
I found lots of large well known business's who have both types do back to back comparisons and their Dyno-Pack read lower by around 8%. I could not believe this because in theory you have less loss through wheels. |
i would thing something is wrong. The greddy kits are really bad kits in terms of power but your running an aem ems with a full 3 inch exhaust system. You should be making at least over 300whp no matter if its a high or low reading dyno. Some dyno pacs read lower than dyno jets and some read higher than dyno jets. Depends on how they setup the dyno and the location of the dyno. I personally dyno at church automotive dyno which uses a dyno pac and they are at sea level and there dyno is known for reading higher than normal.

Are you using a log manifold? If so, consensus is needing a higher then stock vtec (around 7k rpm) engagement point to not have the power drop off prematurely. Could be your main issue.

Thank you to everyone for their insight, help and comments!
