I already have the mac cai n just got the jlt and opted for sonic blue. Does anyone think i should have just kept using the mac n saved my $2** and does anyone else think the craftsman ship on the jlt is a bit cheesy? Mine had pvc shavings all over it, rough edges, spots where they didnt put enough paint on the intake pipe where you can still see the white pvc under the paint and an excessive amount of glue inside the intake pipe.
 
I have a silver one that I bought frm JLT and it looked fine I think the owners name is Jay seemed like a nice guy when I talked to him you should call him and get it replaced...
 
Thanks...
Did you adjust the tps on the throttlebody using a ohm meter if so did it have to be adjusted off the throttlebody or on it..our saleens are pretty close in the mods dept..I'm planning everything you have on your car except that I have added a lightningforce performance heatexchanger..I gained almost 40HP and TQ with the JLT and the heatexchanger plus 96 oct gas..

03 saleen vert/ JLT/Lforce heatexchanger/355 gears/saleen tune.

How did your car respond when you added the 75MM throttlebody I've got one waiting to install plus other mods...
i have my intake and t/b off right now due to warranty issues and im hating every second of it b/c i can definitly feel the difference in power only having my exhaust...and for the tps issue, ive always adjusted mine by hand and never have had any idle adjustment issues and its been on and off about a half a dozen times..

Correct, I just used a multi-meter and adjusted it on the TB. Accufab says not to adjust the set screw, but I had no choice but to back it down because it wouldn't idle below 1500 rpms. I have it set perfect right now with no issues. I had my tuner use the SCT Xcal2 to fine tune the idle (about 600 rpms right now).
