do you think you could safe tune a 5.3L stroked to 383 with 8.1L marine injectors PRC stage 2.5 5.3L heads 11.5:1 compression, fast lsxrt intake and a comp 228/234 112LSA so i could drive it to Sac or would i be better to have it dyno tuned?

 

We can definitely get you tuned, but the Sac tune meet is over so we can get you tuned by mail order.

Feel free to email me at julie@blackbearperformance.com if you'd like more info on the mail order tunes we offer or visit our Tuning Services page.
