[QUOTE="white07psd, post: 545030, member: 1970"] Well, the xtremex, looney wild track and spd early lock up are damn near identical power wise. Theyll all blow my 285s off from a light. Ill actually tow with the xtremex and can manage egts with ease as long as i dont lay into it hard. The Looney track shifts very hard with the lock up and is the smokiest. I run the spd with early lock up daily and it also has the vanes open at idle to give it the non vgt sound. They're all very close tunes and all have early lockup so that generally makes them a hair quicker then a regular race tune. This is all what ive gathered for my truck, every truck responds different with different tunes sent from the stool. [/QUOTE]
