Two things Im thinking, It spins more off the line and the higher shift points may be causing tranny slippage .I really need to get a servo. A part throttle 1 2 shift is crisp and quick but reving to 5800 and shifting seems lazy.Thought you guys would like to see some real world testing. I have never had a custom tune , but it would have to do better than this ****.

What was your MPH on runs with and without the Predator? The trie spin may account for the times being the same but if the Predator had you making more power, I would think you MPH would be higher. I'm not a drag expert but I was told that if a mod gave you more HP, it will show up as a faster MPH.

Sorry , I did not get the mph. Live and learn.I want a nelson tune, but notice my diablo is not for sale. when I had a nitrous hickup. the diag feature saved me a tow bill.

I would reccomend the tuner if you could get it used for a good price as I did. Times are from a beltronics meter, like a g tech.They are really close to the local track times . Thanks for the response guys.
