Been using Jarrad's email maps since 2006 and always been extremely happy with the tunes and Jarrad's advice.
1st map in 2006 to replace cobb stage 2. - More power, smoother, increased response
2nd map in 2007 adding DW 565 injectors, walbro pump and vf39 - Quite a bit more power over PDX/cobb stage 2. Stock drivability.
3rd map was same as second adjusted for 92 octane fuel (moved from east coast to west coast). - not much different from 2nd map (I requested the same tune with only octane adjustment because the last one was perfect.
4th map in 2011 adding an eboost street - a lot more power, much quicker spool time. best one so far
5th map just received adding 68hta, 850cc injectors, up-pipe, turbo-xs FMIC etc.
Jarrad's maps have always been PERFECT for me and I don't expect anything less from this one. Hopefully I can make it down there early in the year to get tuned in person. Wouldn't go anywhere else!
