need more boost. ideas?

So I just got my Jasper engine put in my 97 CC. 3" downpipe, 5" exaust, put a 6637 and a TW chip. Got my A pillar guages all set up. Runs like a raped ape. Now the problem here is that with all that I can only pull about 20 psi of boost. Any ideas? Now I live at about 7000 feet above sea level but I should be able to boost more than 20. Any help would be great. Also my TW chip is a TS? Is he just using them and rewriting them?

More fuel and air only way to push more boost and at that altitude you should be pushing less boost not more vs. sea level. Air is less dense at higher elevation

Yes he pretty much reburns the ts chip, and you need more fuel and air x2, so injectors may help a lot

I am thinking Rosewood stage 2 and a T500. After that I'm thinking a bigger turbo. But right now I think some Meth or an intercoller or both. Just get it all installed before I get the real expensive stuff. Thanks

well, at that altitude, 20 lbs boost w/ stock injectors is very respectable.....

bear in mind that more fuel = more heat.....soooo do the IC first, then injectors ( I run Full Force injectors), then turbo, (the D-66 is a good drop in option) ....
after that, you can tinker on stuff like E-fuel and whatnot.....

you're only going to get just so much gain with the small injectors, so thats the big item.....

Living where you live, 20 PSI boost is good.

I live at 800 foot above sea level and BEFORE the intercooler I was hitting 29 PSI at WOT in my 80HP tune. After the intercooler and in the same tune I am getting 24 PSI at WOT. Both is with stock injectors and stock HPOP.

yep, mine worked out about the ssme MJ .....boost is a way to measure pressure AND restriction.....I used a Banks IC, and less restriction = less "Boost" ..... however it pulled better at 15 lbs boost after the Ic than it did at 20 lbs boost before.....

most of the IC's available, (and the related plumbing), is WAYYYYY better than the factory intake plumbing, which is DEPLORABLE, to say the least.....

I found a 6.0 intercooler on Craigslist for $100. I am going to pick it up this weekend. Looking for a intake spider but there isnt alot of them out there. As for the plumbing, I am thinking I can build something. Thanks for all the help.
