Why the hell am I having so many problems tuning my truck I am using a innovative LC1 I have the fuel sytem to support it everything seems to be good on the istall and to top it off if I go some where else I will have to change the computer back to stock because it is locked and at wot it is still 9.6 to 1 how do you know if the LC1 is reading right?

put it on a dyno and have another wideband put in the exhaust i would say. I have the same wide band and haven't had any problems, hell i have pretty much the exact set up other than my cam and my turbo is MP70 .96 A/R. My tune is SPOT ON. My truck is running like bat out of hell right now in this weather. Good luck Allen is great FI tuner. Good luck hope yours starts running as good as mine soon if you give him a chance i know it will.

Well I would like to give him a chance but I am moving and GM is buying our family vehicle back due to all the problems we have had so my truck will be the primary vehicle probably until I leave and every time I get a retune it takes about a week and a half to get and I have to pay all the shipping which makes no since to me, so at this rate it should be tuned by time we pull our troops out of Iraq!

I have heard alot of good things about stage 6 motorsports over there I guess they specialize in FI most of the guys that I work with that they have done work for have imports!

What's the best way too recal it! and I don't know why my Hyperpac does not read anything but 14.6 to 1 air fuel ratio it starting doing this since I installed the turbo I was going to use it to double check the wide band, oh and I see you have a LS6 cam is that the hot cam kit or just the LS6 cam and did you changed the springs as well, is this good for FI and did you install it yourself?

Well I talked to Allen today he said he is just going to have to keep sending me computers until it gets right and he seems to think that my 9.5 to 1 WOT isn't that bad so decided to get on it a little today still beeing cautious of washing the rings out and besides cutting out a little I manage to do a 2nd and 3rd gear roll over at 60 mph and then tonight when I got off work my boost controller was here so I installed it, first adjustment I overboosted it to 10lbs and then messed with it for a while and finally got it adjusted to 7-8lbs I think it will be bad *** when the tune gets rights now I just need the trans and maybe an LS6 cam, alright and some 22's as well and call it a day!
