Wait, I thought the 5.3L tahoe motor was a LS? Just iron block?

It's LS based but LS1/2/3/4/6/7/9 are just the codes for the motor. The 5.3 truck engine is most commonly LM7 (what I have). Also could be L33, L59, LH6 and a host of other ones depending on year, iron/alum, flex fuel capable, DOD/AFM/VVT, etc.

Jon. When you,say 5k is that just engine and accesories ? Or is that other associated items?

That's to get the car driving.

I thought I would toss in that the ECM software is not cheap either. It was running $200 for a license, don't know what it costs now adays. I would also agree with Jon that a 4L60E will be far more consistant and equally fun to drive. Plus you can tune it and run flappy paddles (if you're into that kind of thing).

I have been looking at,autos now more cause I may want to turbo it later. The softwarei was looking at was about 400 or so. But well worth it for futire upgrades. Also,if you,use painless wiring kit they will flash ecm for free.

Painless Wiring is one of the highest cost rip-off options you can find. A stock engine harness and fuse center is better.

If you want a cheap tune that's close enough then do a mail order tune from Texas Speed. Painless doesn't know jack crap about custom tuning. I bet they just put a stock tune on it, and every ECM you get will have a stock tune already.

I heard you got to have it flashed first to get rid of all the anti theft crap and stuff like that. Also on I side note ill be in f town tomorow.

I can vouch for Painless being anything but painless. Granted, all the wires are there, but the install is very PAINFUL. The harness I had a hand in doing was for a carbureted motor, so should have been easy, but nooo.

Third-ed.

Painless is garbage. Very overpriced, quality lacking, any semblance of logical design lacking as well. Modify the stock stuff or build your own.

Back on topic: If you have a stock ECM then you can do the HPTuners jazz for around $400, or go MegaSquirt for about the same price if you don't.

Id like megasquirt but dont kniw if I am smart enougj

No offense but if you don't feel you're smart enough to get an MS setup going then you're probably not going to be able to modify a stock harness, get it properly installed in the car, and then tune the factory ECM with HPTuner.

I can tune a ecm. I cant build one.

Ya. I've been looking. One thing though that appealed to me while reading gabes thread was the do everything yourself aspect. I may give it a shot.

The factory PCM is really good and has all the safety features and diagnostics built in. I wouldn't built a Mega Squirt unless that's your idea of fun.
