CBRD Tune ECUFlash
Well here's the Dyno sheet.
MODS: K&N Filter, Test Pipe with O2 simulator and UR Catback, ECUFlash
Initial Pull with MODS 243Hp 264Tq
Final Power 311Hp 291Tq
Initial AFR's 9.5
Final AFR's 11.8
Boost reached 23.4 psi
No changes to MIVEC timing
Issues: CEL in second gear WOT goes into limp mode I think. It will idle at 2000 rpm and very little to no boost. Believe its the boost spike around 3400-3500.
Has anyone else had this issue? Any help would be appreciated!!
Chad is doing his best to resolve the issue.

Boost desired engine load tables need to be adjusted. I'm sure Chad will make sure everything is working fine. If not I'll give him grief over AIM.
btw, your base numbers you posted and base numbers on the dyno sheet don't match.

Depending on CEL # you are getting, could either be overboost or airflow limiter table. Most likely overboost because it's spooling much faster.

Yes, everyone that tunes 10's has had to "deal" with the trustful airflow checks tables that lead to the limp mode. They just need to figure out the load you are running AFTER the tune and setup the tables accordingly.

Sound like that dyno reads close to the dyno4mance heart breaker... Good numbers, good work CBRD.

I know Chad will fix my issue and he did say it will give me a check engine light because of the overboost.

CBRD - you said you were able to adjust the MIVEC settings, did you change the boost tables as well? You could probably push a few more PSI based on what others have done so far....
