My car was tuned nearly 6 months ago but since then I've installed new RR's, cam, valvetrain, exhaust, etc. Some of the questions from when I first tuned it threw me for a loop, but I want it done 100% accurate this time. You can see a majority of my mods in my sig, but ask any questions to help me out. Thanks.

Here are the things that I'm not 100% sure about and their options on PCMForLee's order sheet... what should I choose?

Awesome, exactly what I was needing. Haha, I have absolutely no clue why I said something about the MAF, duhh... I remember wondering about that the first time I tuned, but just had a brain fart, forgot about the speed density. Thanks for reminding me .

So can PCMForLess tune the lockup? So 45mph sounds like a good range to set the lockup to?

 

Yea, you can tune for the lockup for the tranny. Stock is like 40-42 and most just go to 45 with it.....some do 50....personal perference.

 

how is the performance with their tunes? im thinking about putting the tpi back on my can and considering a mail order chip or just buy all the burning equipment myself.

 

I've heard great things about them but for $200 or however much it is, you can get the Ostrich for $175(realtime tunable), a wideband, and ALDL stuff for under $350 and tune it yourself. However, some of the numbers I have seen from TPI and LT1 cars are impressive....about 20hp gain for the most part.

 

I'm trying to determine what I want.. For a street/strip car I'm not sure what's ideal.Some say lock right at peak torque RPM, some say lock after xx mph..

Whats your reasons for 45?

My reason for 50 is that its a nice rpm to lockup. I'll be driving in 4th gear and at 49 mph, I am pulling 1600 rpms with 3.73s and 29" tire and its a good rpm in my opinion to lock it up and puts the rpms at 1400 rather than 1000 or 1100 where it used to be. Doesn't seem to struggle.
