260 rwhp (e-shift) @6psi only with a 3" exhaust??Peter Farrell Supercars said:Stage One dynoed at 260 rwhp Auto and 280 rwhp 5 speed (6 psi). This was using a 3" exhaust system and pump gas with safe levels to prevent ping.
We have cranked the boost up to 9 psi and made 300 rwhp (5 sp) but consider it too risky on pump gas.
Stage One is a great building platform for upgrade to Stage Two later, as almost everything is retained in Stage Two.
