I was thinking of having MTI or Ed Wright reprogram my PCM after I do some more intake and exhaust mods. Will they help any on a bolt-on car? If so, who is best as far as performance and reliability? Thanks in advance.

I really wouldn't see the point in having your computer tuned until you started doing some internal mods. Thats just my 2 cents.

The stock program is able to adapt quite well to making external bolt on changes to the car. As mentioned, I wouldn't worry about pcm tuning until you did a cam and heads package or FI.

Alright, thanks. I was just interested in mainly making sure my timing is right on and upping the rev limiter and shift points, but I'll wait a while on it. Will LS1 Edit allow you to change as many things as many times as you want on your secific car? If so, how much is it....$650? Thanks again.

If you go with full bolt-ons, headers, LS6 intake, gears etc then I would consider programming. It eliminates the need for an HPP3, O2 simms and MAFT. At that point, programming becomes very cost efficent and allows for changes beyond what can be accomplished by the HPP3.

If you can wideband dyno tune as part of the programming, it is even better.

I say it is worth it. I have a borla cat-back, Flp's and my computer tuned by Ed. I can honestly say that bang for the buck was the tunning. The borla and FLP's gave me bigger peak hp, but Ed gave me the most tq by far. After the tunning my car was up over 35ft/lbs at 3,000. The biggest difference was 3,250 I think it was 41 ft/lbs. Peak nubers were up 12hp and 19 ft/lbs. Did I mention is is the cheapest mod of the three? The car made more hp and tq all through the rpm's.

I also would recommend custom tuning if you're running just about all of the bolt-ons, especially if you're an A4! The torque mgt. on my SS was bad, and it got even worse with the shift kit. I was also throwing an SES light if idling too long due to a misfire code (thanks to a stock 550 RPM idle), and I didn't have a way to program for the 3.73's. So, I just waited on the 3.73's until I could do custom tuning at the same time. The SOTP difference is considerable, and now my car charges HARD through the shifts without falling on its face. I've been trying to get some new track times for a few weeks, but the weather has yet to cooperate. <img src="gr_images/icons/mad.gif" border="0">

Exactly

Just got my PCM back from Ed. No ses lights (rear o2, egr, air pump, multiple misfires), got rid of that nasty tq converter lock-up situation

Torque converter lock-up situation with the HPP3 that is. I am glad I no longer have to use the HPP3, it scares me <img src="gr_eek2.gif" border="0">
