EPP Blower Cam tuning help
This is what Iv got on the car!
NA LS1 with 317 heads, EPP Blower Cam, LT Headers, LS6 intake, EGR and Cat delete, Ported Throttle Body, and SLP lid(also stock stall )... May be some small odds and ends but those are the main ones!
So I have been trying to get this thing tuned on my own. I under stand some basics(Im Still new to this)... I installed everything on the car and tuned it to run in park and drive. I also dyno tuned it for WOT making 353 whp on a dynojet.
I feel that is very low! So I was wondering if anyone had any suggestions or could help me out? Sometimes get a misfire when cold and the "cruise control" problem!

Is it really missing? the low rev mode misfire tables are zeroed out, repopulate that table with 32767. Smallish cam can require some misfire table tweaks larger numbers
desensitize it. Lower your throttle cracker airflow at speed they are a problem.
Although the stock converter is likely the problem at low speeds with an 800 rpm
idle speed.
353 does sound low what was the AFR on the dyno? How big is this cam?
you are probably just above 9:1 compression

ill adjust the throttle cracker airflow and see how that works. it will Cruise control even around 45mph or it will accelerate on its own up to 45 at times...(how much should i lower throttle cracker?
the Dyno sniffer we had was a POS. it said we were right around 13-14:1 but im running pretty rich still..
Cam specs are: Dur @ .050 232/240 .595/.608lift Lobe Sep 115.0
Thanks for the help!

I made the adjustments on the throttle cracker and misfire table but havent had the chance to see if my misfire problem was fixed... car still has its "cruise control" problem... been tinkering with it abit and seems like nothing is changing to fix it lol...

Misfire will not be fixed all those tables need overhauled for that cam.
353rwh with 6200 rpm stock rev limit, that cam needs more than that.
scale down RAF X .9
The combo of parts you have makes me think a stock Z28 would run circles
around it.
