    Reprogrammed PCM For 3800 (Non Supercharged), 7.6.2021
|
Reviewer: Frank Carnevale (Gainesville, Ga)

Practically plug and play, My 2005 Grand Prix GT started right up, no relearns needed. Huge difference in Tq. And HP. Probably a good 20-30 HP and Tq. Increase. Plus my car runs so much cooler in Temperature. This tune I have to admit for a 16 year old car is amazing.

I have a 2000 Buick Regal GS with a L67. It is a daily driver. I can't believe what this PCM tune did for me. The engine is running as smooth as silk. It just woke that engine up. The shift table is perfect. The hunting for TC lock-up is gone. The "Service Engine Soon" light is gone as well. It is the best $124 I have ever spent on a car. Look no further, this is the one.

I'm lucky enough to live nearby so I took my car over to have the tune done. I mostly wanted to have the fans kick on sooner and stay on after ignition-off. That said, I could not be more happy with the improved shifting behavior and the little bit of extra "oomf" from the extra timing at WOT for 93 octane. Well worth the price of tune for everything that you get with it! This is how the car should have been from the factory!

It burns the tires in 3rd. I had no idea the difference would be this great. So excited! My heads, cam, and intercooler is next. They are the best hands down!

I didn't know what to expect with the different pcm. I have alot of upgrades done to my prix but I honestly must say I noticed the difference as soon as I started the car. They came through with everything they said and the extra things I had them do. I highly recommend buying one. Best bang for my buck yet. Thanks again guys!

Received my Intense PCM yesterday and just finished plugging it in and the damn thing started right up. But went ahead with the case learn anyway. Have a 2002 Regal GS and it's like a new car and haven't even gotten on the gas yet. Have so far a CAI, 3 in DP, front Plog, magnaflow catback, ZZP high velocity TB, ZZP 10mm wires, AL104 180* Tstat. Next to drop down pulley size from 3.6 to 3.4. Nice job Intense you knocked it out of the park

This is by far one of the best things I have bought for my car. The raise shift points make a great difference, along with the ignition timing being advanced, and the higher idling settings have people asking about my car. Most people think it's an LS1 but when I tell them its a V6 their facial expressions are hilarious. I'm also getting better gas mileage as well. Intense-Racing totally knows what they're doing. Thanks again

I bought my original INTENSE PCM for my 02 Impala LS strictly for the performance aspect and noticed some improved drivability as well. When my wife bought her 03 Grand Prix GT, it was one of my "must haves" to keep it running great and strong. Great customer service as well... emails were answered fast and professionally. Thanks again, Intense, for your great products!

I HAVE A 97 PA Ultra with mild mods. The customer service is excellent, shipping is very fast. As soon as I installed the PCM and stepped on the gas I noticed a big difference. I recommend this to anyone.

Definitely a difference in acceleration and overall performance; crisper shifts and quicker off the line - should have made this upgrade long ago.
