Get it tuned right.... you will be happy

 

Thats optimistic. Probably more like 285-295. Stock boost vortechs put down about 300whp and on church they do 330+. My old one did 349 there on stock boost and this one did 346 with the pump out on the aftercooler which totally killed numbers.

 

Damn you guys get such good numbers.

 

At that psi level you have a big over kill with 750cc injectors. Your stock injectors can run proper afr with stock ecu at your current boost level. I would recommend yanking the EMS and larger injectors if you want to get rid of the problem most easily. Your injector size is capable of putting out enough fuel to run 450whp+ so you made a poor choice for your application, either do this or spend more money on chasing down the tuning issue with your ems and have it fixed. Locals in my area have got between 280-310whp with a bone stock ctsc kit with no other modifications and with a Dynojet- which reads in the medium between other dyno meters

 

still no one realizes that the damn dyno reads lower than a jet or pack..

I give up

I was always under the impression the stock injectors maxed out at 300rwhp anyway? Hence why I upgraded to 750's - for future simplicity sake.

The 3.8" pulley is sitting in my boot awaiting install for when I get tired of the stock 7 psi CTSC pulley (which was supposed to be 280rwhp+). I purchased the 750's to save upgrade hassles later on with the 3.8 or even 3.6" pulley (if I ever chose to go that route).

Taking into account, I also have Toda headers, and Invidia Test Pipe with the 70mm V3 exhaust, the numbers should be much greater.

 

750's is way over kill for 300. I know most people like to over-compensate for their setup but jeez. I agree with junky to pull the ems and run stock injectors.

 

I do intend to run higher boost in the very near future, so there's no point in pulling the EMS.... especially not since it owes me nearly $2K.

Different dyno. Different day. Different result.

270rwhp. No changes to the car. Still a Dyno Dynamics....

Apoliges for the lousy night photo.

That run was pulled in 3rd gear, and not 4th.

I've since upgraded to the a 3.8" pulley and belt.

I'm now making 280hp@8.6 psi on a DynoMax dyno.
Vtec engagement set at 3,9K

Mods:
K&N filter
Comptech S/c
Comptech A/cooler (run with coolant)
RC750cc injectors
Toda Headers
Invidia Test Pipe
Invidia V3 exhaust
AEM 1052U ECU

Still disappointed, but not nearly as much as I was when I first installed it all.

Anyone care to shed some light on my situation?
