I feel pretty safe yeah. A/F is in the high 11's, low 12's. At night more like mid 12, and it pulls pretty good.

And that's still tuned for 15PSI, so I only ever get up to around 25-27PSIA now that I'm running 6PSI.

oh iv got an update on my boost controller........i think its dead.......lol

my air filter hits it when i boost hard and its left a nice little dent in the air filter....(injen air filter thats wraped in metal mesh)
the boost controller will work some of the time but will cut out like its a loose power connection....i poped the hood to check it and the wires under the hood are still real solid so it could be a loose connection inside the controller or loose wire under the dash. I used splice connectors for my power so i really dont think thats it but it could just be the switch connections are loose. ill check on it sometime this weekend if i get a chance.

ok iv decided to do the engine build in two parts......i know its going to cost a little more but i suck at saving....lol

im thinking of starting with a pnp head, larger valves, bc stage 2 cam, bc springs, eagle intake mani, larger throttle body.

any suggestions on tb?

next year ill concentrait on the bottem end.......its more expensive and ill have a few things payed off then.....thats kinda the reason for the two part deal.

i say build your bottom first, it will make you get to the boost level you want with your turbo.. you wont be maxing out the stock head setup on low boost level.. cams and intake mani will just be as expensive as rods, pistons

not really......if i had the tools to do my own full engine build id go with that but i was leaning toward p-tuning to do the bottom end and thats a heafty price tage.......iv been trying to get ahold of todd to see what he thought about it and if he might be able to point me in the right direction on someone to build my bottom end but he hasnt responded or answered his calls.
