Lexus isf vs Lexus isf 

A man of wisdom 😂

He does not have the rr tune on his car. He’s running the takeda intake. He plans on getting the intake and tune in the future.

@@tcmcclure2323 ahh ok that makes more sense! would you say the RR tuned intake makes a considerable difference versus a car that is also tuned but on stock intake?

@@YakuzaJZ so before I did headers I ran the stock intake/hps elbow with the JoeZ catback for 7-8 months. I bought my ppe headers and rr intake at the same time but installed the intake and tune around 3 weeks before my headers. I personally did notice a difference (especially in midrange power 3k through 5k rpm) after installing the intake after allowing the kclv to increase back to 26+. I don’t have much data other than that personal experience since I never did a before and after dyno run with stock intake. I did dyno the car the day before headers with the rr intake, hps elbow, and Joe z exhaust and it made 388whp.

@@tcmcclure2323 that’s awesome info man! Thanks! I have cracked stock headers so a great excuse for me to go PPE 😅

@@YakuzaJZ you will love headers. I gained 35whp from headers. 388before with mods mentioned in previous comment and 423whp the following day after headers were installed.
