I guess I don't need tuning. I asked the guy that tuned it and he said go hard. Unless getting 10 PSI it will be fine. He said if I want to he can re-do it, but not necessary. 2 bar MAP table is ready to go. Over my head from there.

 

If it was me, I'd retune it...........better safe than sorry

 

is this because he has already done a radix'ed truck JUST like your with2 bar? Are you still using the maf with your 2 bar or are you really without it?

 

I dunno what the hell I was told from Maggie on the "towing kit/pulley size" I get a different story from everyone I talk to. Botom line I guess is that I have 4.5 PSI, always have, and a 3.2" pulley on pretty stock LQ4. Maybe I should measure crank pulley, I did by truck used. Anyone remember stock OD?

I am hoping with my larger intercooler exchanger and rad that the temps will be okay, since I really only want what a "non-towing" kit would put out. Okay maybe 1 more PSI. Okay maybe 2... but that is it. 3??

I think the non towing is 7 PSI right?

 

at the very least, take some logs

 

stock crank OD is 7.5", however it's not readily apparant by measuring

non towing is whatever pulley it takes to get 6-7 lbs of boost.

 

My pulley looks stock. At least it looks like every other one I've seen. When you say take some logs, you mean just with a scanner, before and after, and make sure it is safe that way, or use a wideband and other stuff?

 

measure the outside diameter of the pulley(blower). Post it up. Grip or blownchevy will set you straight. I can't imagine you have a 3.2. With 4.5psi? But I am no good at the elevation thing either. so..measure and post.

 

I guess he tunes alot of them, sets them up the same and then does his testing with wideband and dyno. If they need changes he makes em to the entire table upwards. He said watch for KR, if it does knock at all it will be okay and go to safer table. Then bring it in for a re-flash. He is a smart dude, I hope I can trust him.

Yes my MAF is not being used.

 

No. I mean the crank pulley looks stock. Blower pulley is a 3.2". Measured it many times now. Wierd though because it is not marked in any way.
