[west_side_supra]

wow that was a great explaination to how that all works, i understand it all now. i did look for a thicker o-ring and i coulndt find jack. thats why i siliconed it, its not mis-fireing/bogging/cutting at all, its driving great, but ill plug up that pipe with the lug nut that the shop forgot to take out of my engine compartment after they were done now for one last question, if i was to get a boost controller how far would i be able to get my stock turbo to push, its only doing 6-7 lbs right now. and also what would be a good boost contoler to get, and im also kinda on a budget right now so maby a cheaper one also thanks again
