ECM Programming Needed?
All,
I've recently performed several performance upgrades and am looking for a custom ECM program to support them. Any recommendations? I have the Predator which I would like to be able to upload and store the custom program on if possible. Here's a list of mods already done. As soon as I can get her running properly she's going in for a dyno run to determine the stall converter requirement and hopefully some gears.
VaraRam II (VR1B) Ram Air Intake System
Granetelli Motorsports Carbon Fiber Air Bridge
2001 C5 MAF w/o Screens
GM Gen. 3 Showroom Stock Racing ASA Heads PN: 88958622 (Lingenfelter CNC Ported)
GM Gen. 3 Showroom Stock Racing ASA Hydraulic Roller Camshaft (.570/.570 @ 239 Intake / 251 Exhaust)
TPiS LT Ceramic Headers
Random Technologies Stainless DualCat 2-3/4" X-Pipe System
GHL Cat Back System w/4x3.5" Bull's-eye Tips
160 Degree Thermostat
Throttle Body Coolant Bypass
Crank (25% Accessory) Underdrive Pulley
NGK V-Power TR-55 Spark Plugs
Thanks!

Re: ECM Programming Needed? (ThePatriot)
Bryan Herter at PCM for less will definetly do the job for you. I owned a 96 impala ss and he reprogrammed my PCM and it made a world of difference. The other programmers such as Hypertech will only change a minimal amount to the pcm which can only be felt at WOT. PCM for less will make more changes to your PCM and you'll feel it through out the rpm range, also he's very involved in dyno testing his programs to make sure that they will produce such horsepower. His prices are also great, about half the cost of other programmers. I think their website is http://www.pcmforless.com . Hope this helps.

The ASA cam is 0.525 lift, 226* /236* int/exh, 110 LSA. The specs you're citing are for the Grand Am (Gib) cam which has a 106 LSA and won't run, very well, closed loop on a stock CI (346) motor.
The heads are the .055" milled SCCA /Grand Am "World Challenge Series " heads. They are not ASA heads.
No flames here. This is NOT an easy tune, closed loop setup . Stroker motor??
FWIW.
