I'm wanting to make my GTP faster. My current mods are SSAC Headers, 3 in. DP, No Cat., No Res., K&N CAI, Stage 1 ZZP Throttle body, 3.4", Gatorback Belt, Plugs & Wires, DHP PCM, 5W-30 Synthetic Oil. I want to further mod my gtp and i have no intentions of doing a cam. I plan on doing both rockers and intercooler. I want to go with yella terra 1.95 roller rockers and 105# springs and retainers. For intercooling I am going to go with Stage 2 WBodyStore Intercooler Kit. Which one should i do first? Should i do rockers now or should i save for intercooler then do rockers later? I will also be getting my blower ported and polished and be getting a 75mm Northstar TB Kit from ZZP. when should i do these mods? What should i do and when? Suggestions welcome. Thanks in advance
